+# Setting the normal and default types lets us keep (almost) the same colors
+# whether the terminal's default colors are white-on-black or black-on-white.
+# It is not exact since the default "white" is not necessarily the same color
+# as the ANSI lightgray, but is as close as we can get in a standard way.
+#
+# If you really want the terminal's default colors, and if lynx is built using
+# ncurses' default-color support, remove these two lines:
+normal: normal: lightgray: blue
+default: normal: white: blue
+
+# Normal type styles correspond to HTML tags.

+# This files contains examples and an explanation for the RULESFILE / RULE
+# feature.
+#
+# Rules for Lynx are experimental. They provide a rudimentary capability
+# for URL rejection and substitution based on string matching.
+# Most users and most installations will not need this feature, it is here
+# in case you find it useful. Note that this may change or go away in
+# future releases of Lynx; if you find it useful, consider describing your
+# use of it in a message to <lynx-dev@nongnu.org>.
+#
+# Syntax:
+# =======
+# Summary of common forms:
+#
+# Fail URL1
+# Map URL1 URL2 [CONDITION]
+# Pass URL1 [URL2] [CONDITION]
+# Redirect URL1 URL2 [CONDITION]
+# RedirectPerm URL1 URL2 [CONDITION]
+# UseProxy URL1 PROXYURL [CONDITION]
+# UseProxy URL1 "none" [CONDITION]
+#
+# Alert URL1 MESSAGE [CONDITION]
+# AlwaysAlert URL1 MESSAGE [CONDITION]
+# UserMsg URL1 MESSAGE [CONDITION]
+# InfoMsg URL1 MESSAGE [CONDITION]
+# Progress URL1 MESSAGE [CONDITION]
+#
+# As you may have guessed, comments are introduced by a '#' character.
+# Rules have the general form
+# Operator Operand1 [Operand2] [CONDITION]
+# with words separated by whitespace. Words containing space can be quoted
+# with "double quotes". Although normally this should not be necessary
+# necessary for URLs, it has to be used for MESSAGE Operands in Alert etc.
+# See below for an explanation of the optional CONDITION.
+#
+# Recognized operators are
+#
+# Fail URL1
+# Reject access to this URL, stop processing further rules.
+#
+# Map URL1 URL2
+# Change the current URL to URL2, then continue processing.
+#
+# Pass URL1 [URL2]
+# Accept this URL and stop processing further rules; if URL2
+# is given, apply this as the last mapping.
+# See the next item for reasons why you generally don't want to "pass"
+# a changed URL.
+#
+# RedirectTemp URL1 URL2
+# RedirectPerm URL1 URL2
+# Redirect [STATUS] URL1 URL2
+# Stop processing further rules and redirect to URL2, just as if lynx had
+# received a HTTP redirection with URL2 as the new location. This means that
+# URL2 is subject to any applicable permission checking, if it passes a new
+# request will be issued (which may result in a new round of rules checking,
+# with a new "current URL") or the new URL might be taken from the cache, and,
+# after successful loading, lynx's idea of what the loaded document's URL is
+# will be fully updated. All this does not happen if you just "pass" a changed
+# URL (or let it fall through), so this is generally the preferred way for
+# substituting URLs.
+# If the RedirectPerm variant is used, or if the optional word is supplied and
+# is either "permanent" or "301", act as if lynx had received a permanent
+# redirection (with HTTP status 301). In most cases this will not make a
+# noticeable difference. Lynx may cache the location in a special way for 301
+# redirections, so that the redirection is followed immediately the next time
+# the same original URL is accessed, without re-checking of rules. Therefore
+# the permanent variant should never be used if the desired outcome of rules
+# processing depends on variable conditions (see CONDITIONS below) or on
+# setting a special flag (see next item).
+#
+# PermitRedirection URL1
+# Mark following redirection as permitted, and continue processing. Some
+# redirection locations are normally not allowed, because permitting them in a
+# response from an arbitrary remote server would open a security hole, and
+# others are not allowed if certain restrictions options are in effect. Among
+# redirection locations normally always forbidden are lynxprog: and lynxexec:
+# schemes. With "default" anonymous restrictions in effect, many URL schemes
+# are disallowed if the user would not be allowed to use them with 'g'oto.
+# This rule allows to override the permission checking if rules processing ends
+# with a Redirect (including the RedirectPerm or RedirectTemp forms). It is
+# ignored otherwise, in particular, it does not influence acceptance if rules
+# processing ends with a "Pass" and a real redirection is received in the
+# subsequent HTTP request. If redirections are chained, it only applies to the
+# redirection that ends the same rules cycle. Note that the new URL is still
+# subject to other permission checks that are not specific to redirections; but
+# using this rule may still weaken the expected effect of -anonymous,
+# -validate, -realm, and other restriction options, including TRUSTED_EXEC and
+# similar in lynx.cfg, so be careful where you redirect to if restrictions are
+# important!
+#
+# UseProxy URL1 PROXYURL
+# Stop processing further rules, and force access through the proxy given by
+# PROXYURL. PROXYURL should have the same form as required for foo_proxy
+# environment variables and lynx.cfg options, i.e., (unless you are trying to
+# do something unusual) "http://some.proxy-server.dom:port/". This rule
+# overrides any use of a proxy (or external gateway) that might otherwise apply
+# because of environment variables or lynx.cfg options, it also overrides any
+# "no_proxy" settings.
+#
+# UseProxy URL1 none
+# Mark request as NOT using any proxy (or external gateway), and continue
+# processing(!). For a request marked this way, any subsequent UseProxy
+# rule with a PROXYURL will be ignored, and any use of a proxy (or external
+# gateway) that might otherwise apply because of environment variables or
+# lynx.cfg options will be overridden. Note that the marking will not
+# survive a Redirect rule (since that will result, if successful, in a
+# new request).
+#
+# Alert URL1 MESSAGE
+# AlwaysAlert URL1 MESSAGE
+# UserMsg URL1 MESSAGE
+# InfoMsg URL1 MESSAGE
+# Progress URL1 MESSAGE
+# These produce various kinds of statusline messages, differing in whether
+# a pause is enforced and in its duration, immediately when the rule is
+# applied. AlwaysAlert shows the message text even in non-interactive mode
+# (-dump, -source, etc.). Rule processing continues after the message is
+# shown. As usual, these rules only apply if URL1 matches. MESSAGE is
+# the text to be displayed, it can contain one occurrence of "%s" which
+# will be replaced by the current URL, literal '%' characters should be
+# doubled as "%%".
+#
+# Rules are processed sequentially first to last for each request, a rule
+# applies if the current URL matches URL1. The current URL is initially the
+# URL for the resource the user is trying to access, but may change as the
+# result of applied Map rules. case-sensitive (!) string comparison is used,
+# in addition URL1 can contain one '*' which is interpreted as a wildcard
+# matching 0 or more characters. So if for example
+# "http://example.com/dir/doc.html" is requested, it would match any of
+# the following:
+# Pass http:*
+# Pass http://example.com/*.html
+# Pass http://example.com/*
+# Pass http://example*
+# Pass http://*/doc.html
+# but not:
+# Pass http://example/*
+# Pass http://Example.COM/dir/doc.html
+# Pass http://Example.COM/*
+#
+# If a URL2 is given and also contains a '*', that character will be
+# replaced by whatever matched in URL1. Processing stops with the
+# first matching "Fail" or "Pass" or when the end of the rules is reached.
+# If the end is reached without a "Fail" or "Pass", the URL is allowed
+# (equivalent to a final "Pass *").
+#
+# The requested URL will have been transformed to Lynx's normal
+# representation. This means that local file resources should be
+# expected in the form "file://localhost/<path using slash separators>",
+# not in the machine's native representation for filenames.
+#
+# Anyone with experience configuring the venerable CERN httpd server will
+# recognize some of the syntax - in fact, the code implementing rules goes
+# back to a common ancestor. But note the differences: all URLs and URL-
+# patterns here have to be given as absolute URLs, even for local files.
+# (Absolute URLs don't imply proxying.)
+#
+# CONDITIONS
+# ----------
+# All rules mentioned can be followed by an optional CONDITION, which can
+# be used to further restrict when the rule should be applied (in addition
+# to the match on URL1). A CONDITION takes one of the forms
+# "if" CONDITIONFLAG
+# "unless" CONDITIONFLAG
+# and currently two condition flags are recognized:
+# "userspecified" (or abbreviated "userspec")
+# "redirected"
+# To explain these, first some terms need to be defined. A "request"
+# is...
+#
+# A user action (like following a link, or entering a 'g'oto URL) can either be
+# rejected immediately (for example, because of restrictions in effect, or
+# because of invalid input), or can generate a "request". For the purpose of
+# this discussion, a "request" is the sequence of processing done by lynx,
+# which might ultimately lead to an actual network request and loading and
+# display of data; a request can also result in rejection (for example, some
+# restrictions are checked at this stage), or in a redirection. A redirection
+# in turn can be rejected (which makes the request fail), or can automatically
+# generate a new request. A "request chain" is the sequence of one or more
+# requests triggered by the same user event that are chained together by
+# redirections.
+# For each request, some URL schemes are handled (or rejected) specially, see
+# Limitation 1 below, the others are passed to the generic access code. Rules
+# processing occurs at the beginning of the generic access code, before a
+# request is dispatched to the scheme-specific protocol module (but after
+# checking whether the request can be satisfied by re-displaying an already
+# cached document).
+# With these definitions, the meaning of the possible CONDITIONFLAGS:
+#
+# if redirected
+# The rule applies if the current request results from a redirection;
+# whether that was a real HTTP redirection or one generated by a rule
+# in the previous request makes no difference. In other words, the
+# condition is true if the current request is not the first one in the
+# request chain.
+#
+# if userspecified
+# The rule applies if the initial URL of the request chain was specified
+# by the user. Lynx marks a request as "user specified" for URLs that
+# come from 'g'oto prompts, as well as for following links in a bookmark
+# or Jump file and some other special (lynx-generated) pages that may
+# contain URLs that were typed in by the user.
+# Note that this is not a property of the request, but of the whole request
+# chain (based on where the first request's URL came from). The current
+# URL may differ from what the user typed
+# - because of initial fixups, including conversion of Guess-URLs and file
+# paths to full URLs,
+# - because of Map rules applied, and/or
+# - because of a previous redirection.
+# So to make reasonably sure a suspicious or potentially dangerous URL has
+# been entered by the user, i.e. is not a link or external redirection
+# location that cannot be trusted, a combination of "userspecified" and
+# "redirected" flags should be used, for example
+# Fail URL1 unless userspecified
+# Fail URL1 if redirected
+# ...
+#
+# CAVEAT
+# ======
+# First, to squash any false expectations, an example for what NOT TO DO.
+# It might be expected that a rule like
+# Fail file://localhost/etc/passwd # <- DON'T RELY ON THIS
+# could be used to prevent access to the file "/etc/passwd". This might
+# fool a naive user, but the more sophisticated user could still gain
+# access, by experimenting with other forms like (@@@ untested)
+# "file://<machine's domain name>/etc/passwd" or "/etc//passwd"
+# or "/etc/p%61asswd" or "/etc/passwd?" or "/etc/passwd#X" and so on.
+# There are many URL forms for accessing the same resource, and Lynx
+# just doesn't guarantee that URLs for the same resource will look the
+# same way.
+#
+# The same reservation applies to any attempts to block access to unwanted
+# sites and so on. This isn't the right place for implementing it.
+# (Lynx has a number of mechanisms documented elsewhere to restrict access,
+# see the INSTALLATION file, lynx.cfg, lynx -help, lynx -restrictions.)
+#
+# Some more useful applications:
+#
+# 1. Disabling URLs by access scheme
+# ----------------------------------
+# Fail gopher:*
+# Fail finger:*
+# Fail lynxcgi:*
+# Fail LYNXIMGMAP:*
+# This should work (but no guarantees) because Lynx canonicalizes
+# the case of recognized access schemes and does not interpret
+# %-escaping in the scheme part (@@@ always?)
+#
+# Note that for many access schemes Lynx already has mechanisms to
+# restrict access (see lynx.cfg, -help, -restrictions, etc.), others
+# have to be specifically enabled. Those mechanisms should be used
+# in preference.
+# Note especially Limitation 1 below.
+# This can be used for the remaining cases, or in addition by the
+# more paranoid. Note that disabling "file:*" will also make many
+# of the special pages generated by lynx as temporary files (INFO,
+# history, ...) inaccessible, on the other hand it doesn't prevent
+# _writing_ of various temp files - probably not what you want.
+#
+# You could also direct access for a scheme to a brief text explaining
+# why it's not available:
+# Redirect news:* http://localhost/texts/newsserver-is-broken.html
+#
+# 2. Preventing accidental access
+# -------------------------------
+# If there is a page or site you don't want to access for whatever
+# reason (say there's a link to it that crashes Lynx [don't forget to
+# report a bug], or if that starts sending you a 5 Mb file you don't
+# want, or you just don't like the people...), you can prevent yourself
+# from accidentally accessing it:
+# Fail http://bad.site.com/*
+#
+# 3. Compressed files
+# -------------------
+# You have downloaded a bunch of HTML documents, and compressed them
+# to save space. Then you discover that links between the files don't
+# work, because they all use the names of the uncompressed files. The
+# following kind of rule will allow you to navigate, invisibly accessing
+# the compressed files:
+# Map file://localhost/somedir/*.html file://localhost/somedir/*.html.gz
+# or, perhaps better:
+# Redirect file://localhost/somedir/*.html file://localhost/somedir/*.html.gz
+#
+# 4. Use local copies
+# -------------------
+# You have downloaded a tree of HTML documents, but there are many links
+# between them that still point to the remote location. You want to access
+# the local copies instead, after all that's why you downloaded them. You
+# could start editing the HTML, but the following might be simpler:
+# Map http://remote.com/docs/*.html file://localhost/home/me/docs/*.html
+# Or even combine this with compressing the files:
+# Map http://remote.com/docs/*.html file://localhost/home/me/docs/*.html.gz
+#
+# Again, replacing the "Map" with "Redirect" is probably better - it will
+# allow you to see the _real_ location on the lynx INFO screen or in the
+# HISTORY list, will avoid duplicates in the cache if the same document is
+# loaded with two different URLs, and may allow you to 'e'dit the local
+# from within lynx if you feel like it.
+#
+# 5. Broken links etc.
+# --------------------
+# A user has moved from http://www.siteA.com/~jdoe to http://siteB.org/john,
+# or http://www.provider.com/company/ has moved to their own server
+# http://www.company.com, but there are still links to the old location
+# all over the place; they now are broken or lead to a stupid "this page
+# has moved, please update your bookmarks. Refresh in 5 seconds" page
+# which you're tired of seeing. This will not fix your bookmarks, and
+# it will let you see the outdated URLs for longer (Limitation 3 below),
+# but for a quick fix:
+# Redirect http://www.siteA.com/~jdoe/* http://siteB.org/john/*
+# Redirect http://www.provider.com/company/* http://www.company.com/*
+#
+# You could use "Map" instead of "Redirect", but this would let you see the
+# outdated URLs for longer and even bookmark them, and you are likely to
+# create invalid links if not all documents from a site are mapped
+# (Limitation 3).
+#
+# 6. DNS troubles
+# ---------------
+# A special case of broken links. If a site is inaccessible because the
+# name cannot be resolved (your or their name server is broken, or the
+# name registry once again made a mistake, or they really didn't pay in
+# time...) but you still somehow know the address; or if name lookups are
+# just too slow:
+# Map http://www.somesite.com/* http://10.1.2.3/*
+# (You could do the equivalent more cleanly by adding an entry to the hosts
+# file, if you have access to it.)
+#
+# Or, if a name resolves to several addresses of which one is down, and the
+# DNS hasn't caught up:
+# Map http://www.w3.org/* http://www12.w3.org/*
+#
+# Note that this can break access to some name-based virtually hosted sites.
+#
+# In this case use of "Map" is probably preferred over "Redirect", as long
+# as the URL on the left side contains the real and preferred hostname or
+# the problem is only temporary.
+#
+# 7. Avoid redirections
+# ---------------------
+# Some sites have a habit to provide links that don't go to the destination
+# directly but always force redirection via some intermediate URL. The
+# delay imposed by this, especially for users with slower connections and
+# for overloaded servers, can be avoided if the intermediate URLs always
+# follow some simple pattern: we can then anticipate the redirect that will
+# inevitably follow and generate it internally. For example,
+# Redirect http://lwn.net/cgi-bin/vr/* http://*
+#
+# Warning: The page authors may not like this circumvention. Often the
+# redirection is wanted by them to track access, sometimes in connection
+# with cookies. Some sites may employ mechanisms that defeat the shortcut.
+# It is your responsibility to decide whether use of this feature is
+# acceptable. (But note that the same effect can be achieved anyway for
+# any link by editing the URL, e.g. with the ELGOTO ('E') key in Lynx, so
+# a shortcut like this does not create some new kind of intrusion.)
+#
+# 8. Detailed proxy selection
+# ---------------------------
+# Basic use for this one should be obvious, if you have a need for it.
+# It simply allows selecting use (or non-use) of proxies on a more detailed
+# level than the traditional <scheme>_proxy and no_proxy variables, as well
+# as using different proxies for different sites.
+# For example, to request access through an anonymizing proxy for all pages
+# on a "suspicious" site:
+# UseProxy http://suspicious.site/* http://anonymyzing.proxy.dom/
+# (as long as all URLs really have a matching form, not some alternative
+# like <http://suspicious.site:80/> or <http://SuSpIcIoUs.site/>!)
+#
+# To access some site through a local squid proxy, running on the same host
+# as lynx, except for some image types (say because you rarely access images
+# with lynx anyway, and if you do, you don't want them cached by the proxy):
+# UseProxy http://some.site/*.gif none
+# UseProxy http://some.site/*.jpg none
+# UseProxy http://some.site/* http://localhost:3128/
+# Note that order is important here.
+#
+# To exempt a local address from all proxying:
+# UseProxy http://local.site/* none
+#
+# Note however that for some purposes the "no_proxy" setting may be better
+# suited than "UseProxy ... none", because of its different matching logic
+# (see comments in lynx.cfg).
+#
+# 9. Invent your own scheme
+# -------------------------
+# Suppose you want to teach lynx to handle a completely new URL scheme.
+# If what's required for the new scheme is already available in lynx in
+# _some_ way, this may be possible with some inventive use of rules.
+# As an example, let's assume you want to introduce a simple "man:" scheme
+# for showing manual pages, so (for a Unix-like system, at least) "man:lynx"
+# would display the same help information as the "man lynx" command and so
+# on (we ignore section numbers etc. for simplicity here).
+# First, since lynx doesn't know anything about a "man:" scheme, it will
+# normally reject any such URLs at an early stage. However, a trick exists
+# to bypass that hurdle: define a man_proxy environment variable *outside of
+# lynx, before starting lynx* (it won't work in lynx.cfg), the actual value
+# is unimportant and won't actually be used. For example, in your shell:
+# export man_proxy=X
+#
+# If you already have some kind of HTTP-accessible man gateway available,
+# the task then probably just amounts to transforming the URL into the right
+# form. For one such gateway (in this case, a CGI script running on the
+# local machine), the rule
+# Redirect man:* http://localhost/cgi-bin/dwww?type=runman&location=*/
+# or, alternatively,
+# UseProxy man:* none
+# Map man:* http://localhost/cgi-bin/dwww?type=runman&location=*/
+# does it, for other setups the right-hand side just has to be modified
+# appropriately. The "UseProxy" is to make sure the bogus man_proxy gets
+# ignored.
+#
+# If no CGI-like access is available, you might want to invoke your system's
+# man command directly for a man: URL. Here is some discussion of how this
+# could be done, and why ultimately you may not want to do it; this is also
+# an opportunity to show examples for how some of the rules and conditions
+# can be used that haven't been discussed in detail elsewhere.
+# Lynx provides the lynxexec: (and the similar lynxprog:) scheme for running
+# (nearly) arbitrary commands locally. At the heart of employing it for
+# man: would be a rule like this:
+# Redirect man:* "lynxexec:/usr/bin/man *"
+# (It is a peculiarity of this scheme that the literal space and quoting
+# are necessary here. Also note that Map cannot be used here instead of
+# Redirect, since lynxexec, as a special kind of URL, needs to be handled
+# "early" in a request.)
+# Of course, execution of arbitrary commands is a potentially dangerous
+# thing. lynxexec has to be specifically enabled at compile time and in
+# lynx.cfg (or with command line options), and there are various levels
+# of control, too much to go into here. It is assumed in the following that
+# lynxexec has been enabled to the degree necessary (allow /usr/bin/man
+# execution) but hopefully not too much.
+# What needs to be prevented is that allowing local execution of the man
+# command might unintentionally open up unwanted execution of other commands,
+# possibly by some trick that could be exploited. For example, redirecting
+# man:* as above, the URL "man:lynx;rm -r *" could result in the command
+# "man lynx;rm -r *" executed by the system, with obvious disastrous results.
+# (This particular example won't actually work, for several reasons; but
+# for the purpose of discussion let's assume it did, there may be similar
+# ones that do.)
+# Because of such dangers, redirection to a lynxexec: is normally never
+# accepted by lynx. We need at least a PermitRedirection rule to override
+# this protective limitation:
+# PermitRedirection man:*
+# Redirect man:* "lynxexec:/usr/bin/man *"
+# But now we have potentially opened up local execution more than is
+# acceptable via the man: scheme, so this needs to be examined.
+# There are two aspects to security here: (1) restricting the user, and (2)
+# protecting the user. The first could also be phrased as protecting the
+# system from the user; the second as preventing lynx (and the system) from
+# doing things the user doesn't really want. Aspect (1) is very important
+# for setups providing anonymous guest accounts and similarly restricted
+# environments. (Otherwise shell access is normally allowed, and trying to
+# protect the system in lynx would be rather pointless.) As far as access
+# to some URLs is concerned, the difference can be characterized in terms of
+# which sources of URLs are trusted enough to allow access: for (1), only
+# links occurring in a limited number of documents are trusted enough for
+# some (or all) URLs, user input at 'g'oto prompts and the like is not (if
+# not completely disabled). For (2) and assuming a user with normal shell
+# privileges, the user may be trusted enough to accept any URL explicitly
+# entered, but URLs from arbitrary external sources are not - someone might
+# try to use them to trick the user (by following an innocent-looking link)
+# or lynx (by following a redirection) into doing something undesirable.
+#
+# In the following we are concerned with (2); it is assumed that providers
+# of anonymous accounts would not want to follow this path, and would have
+# no need for additional schemes that imply local execution anyway. (For
+# one thing, with the man example they would have to carefully check that
+# users cannot break out of the man command to a local shell prompt.)
+#
+# Getting back to the example, it was already mentioned that lynx does not
+# allow redirections to lynxexec. In fact this continues to be disallowed
+# for real redirection received from HTTP servers. But we have introduced
+# a new man: scheme, and the lynx code that does the redirection checking
+# doesn't know anything about special considerations for man: URLs, so
+# an external HTTP server might send a redirection message with "Location:
+# man:<something>", which lynx would allow, and which would in turn be
+# redirected by our rule to "lynxexec:/usr/bin/man <something>". Unless
+# we are 100% sure that either this can never happen or that the lynxexec
+# URL resulting from this can have no harmful effect, this needs to be
+# prevented. It can be done by checking for the "redirected" condition,
+# either by putting something like (the first line is of course optional)
+# Alert man:* "Redirection to man: not allowed" if redirected
+# Fail man:* if redirected
+# somewhere before the Redirect rule, or, reversing the logic, by adding
+# a condition to the redirection rules, i.e. they become
+# PermitRedirection man:* unless redirected
+# Redirect man:* "lynxexec:/usr/bin/man *" unless redirected
+# (actually, putting the condition on either one of the rules would be
+# sufficient). The second variant assumes that the attempted access to
+# man: via redirection will ultimately fail because there is no other way
+# to handle such URLs.
+#
+# The above should take care of rejecting man: URLs from redirections, but
+# what about regular links in HTML (like <A HREF="man:...">)? As long as
+# it can be assumed that the user will always inspect each and every link
+# before following it, and never follow a link that can have harmful effect,
+# no further restrictions are necessary. But this is a very big assumption,
+# unrealistic except perhaps in some single-user setups where the user is
+# is identical with the rule writer. So normally most links have to be
+# regarded as suspect, and only URLs entered by the user can be accepted:
+# Alert man:* "Redirection to man: not allowed" if redirected
+# Fail man:* if redirected
+# Alert man:* "Link to man: not allowed" unless userspecified
+# Fail man:* unless userspecified
+#
+# With these restrictions we have limited the ways our new man: scheme can
+# be used rather severely, to the point where its usefulness is questionable.
+# In addition to 'g'oto prompts, it may work in Jump files; also, should
+# links to man:<something> appear in HTML text, the user could retype them
+# manually or use the ELGOTO ('E') command with some trivial editing (like
+# adding a space) to "confirm" the URL. Even if the precautions outlined
+# above are followed: THIS TEXT DOES NOT IMPLY ANY PROMISE THAT, BY FOLLOWING
+# THE EXAMPLES, LYNX WILL BE SAFE. On the other hand, some of the precautions
+# *may* not be necessary: it is possible that careful use of TRUSTED_EXEC
+# options in lynx.cfg could offer enough protection while making the new
+# scheme more useful.
+#
+# If all this seems a bit too scary, that's intentional; it should be noted
+# that these considerations are not in general necessary for "harmless" URL
+# schemes, but appropriate for this "extreme" example. One last remark
+# regarding the hypothetical man scheme: instead of implementing it through
+# "lynxexec:" or "lynxprog:", it would be somewhat safer to use "lynxcgi:"
+# instead if it is supported. A simple lynxcgi script would have to write
+# the man page to stdout (either converted to text/html or as plain text,
+# preceded by an appropriate Content-Type header line), and all necessary
+# checking for special shell characters would be done within the script -
+# lynx does not use the system() function to run the script.
+#
+# Other Limitations
+# =================
+# First, see CAVEAT above. There are other limitations:
+#
+# 1. Applicable URL schemes
+# -------------------------
+# Rules processing does not apply to all URL schemes. Some are
+# handled differently from the generic access code, therefore rules
+# for such URLs will never be "seen". This limitation applies at
+# least to lynxexec:, lynxprog:, mailto:, LYNXHIST:, LYNXMESSAGES:,
+# LYNXCFG:, and LYNXCOMPILEOPTS: URLs. You shouldn't be tempted
+# to try to redirect most of these schemes anyway, but this also
+# makes it impossible to disable them with "Fail" rules.
+#
+# Also, a scheme has to be known to Lynx in order to get as far as
+# applying rules - you cannot just define your own new foobar: scheme
+# and then map it to something here, but see Application 9, above,
+# for a workaround.
+#
+# 2. No re-checking
+# -----------------
+# When a URL is mapped to a different one, the new URL is not checked
+# again for compliance with most restrictions established by -anonymous,
+# -restrictions, lynx.cfg and so on. This can be regarded as a feature:
+# it allows specific exceptions. Of course it means that users for
+# whom any restrictions must be enforced cannot have write access to a
+# personal rules file, but that should be obvious anyway!
+# This limitation does not applies if "Redirect" is used, in that case
+# the new URL will always be re-examined.
+#
+# 3. Mappings are invisible
+# -------------------------
+# Changing the URL with "Map" or "Pass" rules will in general not be
+# visible to the user, because it happens at a late stage of processing
+# a request (similar to directing a request through a proxy). One
+# can think of two kinds of URL for every resource: a "Document URL" as
+# the user sees it (on INFO page, history list, status line, etc.), and
+# a "physical URL" used for the actual access. Rules change only the
+# physical URL. This is different from the effect of HTTP redirection.
+# Often this is bad, sometimes it may be desirable.
+#
+# Changing the URL can create broken links if a document has relative URLs,
+# since they are taken to be relative to the "Document URL" (if no BASE tag
+# is present) when the HTML is parsed.
+#
+# This limitation does not apply if "Redirect" is used - the new location
+# will be visible to the user, and will be used by lynx for resolving
+# relative URLs within the document.
+#
+# 4. Interaction with proxying
+# ----------------------------
+# Rules processing is done after most other access checks, but before
+# proxy (and gateway) settings are examined. A "Fail" rule works
+# as expected, but when the URL has been mapped to a different one,
+# the subsequent proxy checking can get confused. If it decides that
+# access is through a proxy or gateway, it will generally use the
+# original URL to construct the "physical" URL, effectively overriding
+# the mapping rules. If the mapping is to a different access scheme
+# or hostname, proxy checking could also be fooled to use a proxy when
+# it shouldn't, to not use one when it should, or (if different proxies
+# are used for different schemes) to use the wrong proxy. So "just
+# don't do that"; in some cases setting the no_proxy variable will help.
+# Example 3 happens to work nicely if there is a http_proxy but no
+# ftp_proxy.
+#
+# This limitation does not come into play if a "UseProxy" rule is applied,
+# in either of its two forms: with a PROXYURL, proxying is fully under
+# the control of the rules author, and with "none", subsequent proxy
+# and gateway checking is completely disabled. It is therefore a good
+# idea to combine any "Map" and "Pass" rules that might result in passing
+# the changed URL with explicit "UseProxy" rules, if the rules file is
+# expected to be used together with proxying; or else always use "Redirect"
+# instead of simple passing.
+#
+# 5. Case-sensitive matching
+# --------------------------
+# The matching logic is generic string-based. It doesn't know anything
+# about URL syntax, and so it cannot know in which parts of a URL case
+# matters and where it doesn't. As a result, all comparisons are case-
+# sensitive. If (a limited number of) case variations of a URL need
+# to be dealt with, several rules can be used instead of one.
+# In particular, this makes "UseProxy ... none" in some ways more limited
+# than a no_proxy setting.
+#
+# 6. Redirection differences
+# --------------------------
+# For some URLs lynx does never check after a request whether a redirection
+# occurs; that makes the "Redirect" rule useless for such URLs (in addition
+# to those mentioned under limitation 1.). Some of them are some gopher
+# types, telnet: and similar in most situations, newspost: and similar,
+# lynxcgi:, and some other private types. Trying to redirect these will
+# make access fail. You probable don't want to change such URLs anyway,
+# but if you feel you must, try using "Map" and "Pass" instead.
+#
+# The -noredir command line option only applies for real HTTP redirection
+# responses, Redirect rules are still applied. Also for certain other
+# command line options (-mime_header, -head) and command keys (HEAD) lynx
+# shows the redirection message (or part of it) in case of a real HTTP
+# redirection, instead of following the redirection. Here, too, a Redirect
+# rule remains effective (there is no redirection message to show, after all).
+#
+# 7. URLs required
+# ----------------
+# Full absolute URLs (modulo possible "*" matching wildcards) are required
+# in rules. Strings like "www.somewhere.com" or "/some/dir/some.file" or
+# "www.somewhere.com/some/dir/some.file" are not URLs. Lynx may accept
+# them as user input, as abbreviated forms for URLs; but by the time the
+# rules get checked, those have been converted to full URLs, if they can
+# be recognized. This also means that rules cannot influence which strings
+# typed at a 'g'oto prompt are recognized for URLs - rules processing kicks
+# in later.

+# $LynxId: lynx-keymaps,v 1.7 2013/10/13 20:40:00 tom Exp $
+#
+# This is a sample key sequence definition file. It is used by Lynx when
+# built with ncurses or slang, to augment the definitions from your terminal's
+# termcap or terminfo description.
+
+# (Lynx implements this mechanism only if USE_KEYMAPS is defined during
+# compilation, which has nothing to do with the KEYMAP directives in lynx.cfg,
+# see source file LYCurses.h.)
+
+# Lines that start with a '#' are comment lines. Blank lines are ignored.
+
+# The 'setkey' function may be used in two ways:
+#
+# 1. setkey ESC-SEQUENCE KEYSYM
+# 2. setkey ESC-SEQUENCE KEYSYM_NAME
+#
+# where KEYSYM is an integer. A keysym is essentially with the lynx.cfg
+# file calls a 'keystroke', but I think that keysym is a more appropriate
+# name. The keysym is an integer and may be expressed in various ways:
+#
+# as a decimal integer: 97
+# hexadecimal: 0x61
+# Octal: 0141
+# as an ASCII character: 'a'
+#
+# Some keysyms may be expressed symbolically as a keysym name using the
+# second form. The currently recognized symbolic names are:
+#
+# UPARROW
+# DNARROW
+# RTARROW
+# LTARROW
+# PGDOWN
+# PGUP
+# HOME
+# END
+# F1
+# F2
+# F3
+# F4
+# F5
+# F6
+# F7
+# F8
+# F9
+# F10
+# F11
+# F12
+# DO_KEY
+# FIND_KEY
+# SELECT_KEY
+# INSERT_KEY
+# REMOVE_KEY
+# DO_NOTHING
+#
+# It does not matter if your keyboard does not have some of the keys
+# implied by the above names. The fact is that lynx uses these keys as an
+# an intermediate representation.
+#
+# The ESC-SEQUENCE should be enclosed in double quotes. The '^' character
+# is special and indicates a control character, e.g., ^K is Ctrl-K. An ESC
+# character (ascii 27) may be represented as ^[. As an example, many
+# terminals have arrow keys that emit 'ESC [ A' for the UP arrow. This may
+# be represented as the escape sequence "^[[A". The default keymapping is
+# given below:
+#
+setkey "\033[A" UPARROW
+setkey "\033OA" UPARROW
+setkey "\033[B" DNARROW
+setkey "\033OB" DNARROW
+setkey "\033[C" RTARROW
+setkey "\033OC" RTARROW
+setkey "\033[D" LTARROW
+setkey "\033OD" LTARROW
+setkey "\033[1~" FIND_KEY
+setkey "\033[2~" INSERT_KEY
+setkey "\033[3~" REMOVE_KEY
+setkey "\033[4~" SELECT_KEY
+setkey "\033[5~" PGUP
+setkey "\033[6~" PGDOWN
+setkey "\033[8~" END
+setkey "\033[7~" HOME
+setkey "\033[28~" F1
+setkey "\033[29~" DO_KEY
+#
+# All other keys map to themselves, e.g,
+#
+setkey "a" 'a'
+#
+# Now suppose that your terminal produces different escape sequences for
+# HOME and END. In particular, suppose that the home key produces 'ESC [
+# H' and that the end key produces 'ESC [ K'. Then these may be defined to
+# map to lynx HOME and END keys via
+#
+setkey "^[[H" HOME
+setkey "^[[K" END
+#
+# Similarly, we may map emacs-like sequences to these functions:
+#
+setkey "^[<" HOME
+setkey "^[>" END
+#
+# Note that it may be impossible to map several sequences to the same
+# keysym (NCURSES only?), in that case the mapping occurring last wins.
+#
+# The following maps a sequence commonly used for Shift+Tab to the
+# corresponding code. It should not be needed if the terminfo file
+# has the correct info for kcbt.
+#
+setkey "^[[Z" 0x10F
+#
+# Other special escapes:
+# \a bell
+# \b backspace
+# \f form-feed
+# \n newline (line-feed)
+# \r carriage-return
+# \t tab
+# \v vertical tab
+# \<number> octal number, up to 3 digits, e.g., "\033".
+# \d<number> decimal number, up to 3 digits, e.g., "\d99"
+# \x<number> hexadecimal number, up to 2 digits, e.g., "\xFF"
+#
+# For Unix-systems (which have termcap or terminfo) you may also use symbols
+# that refer to the termcap/terminfo, by referencing the name bracketed by
+# "^(" and ")", e.g.,
+setkey "^(cuu1)" UPARROW
+setkey "^(up)" UPARROW
+#
+# The following extension, introduced after lynx2.8.2, allows to force
+# recognition of meta (ESC) prefixes - especially useful with the
+# "Bash-like" lineeditor binding. Its use is unnecessary in most
+# cases if Lynx was built with ncurses, but is probably necessary for
+# all keys that should recognize ESC as a prefix if Lynx was built with
+# slang.
+#
+# setkey ESC-SEQUENCE Meta-LETTER
+# setkey ESC-SEQUENCE Meta-KEYSYM
+# setkey ESC-SEQUENCE Meta-KEYSYM_NAME
+#
+# for example
+#setkey "\033b" Meta-b
+#setkey "\033e" Meta-'e'
+#setkey "\033\033[28~" Meta-F1
+#
+# The following extensions, introduced after lynx2.8.2, allow mapping
+# escape sequences directly to key commands (lynxactioncodes).
+#
+# setkey ESC-SEQUENCE LAC:LYNX_ACTION
+# setkey ESC-SEQUENCE LAC:LYNX_ACTION:LYNX_EDITACTION
+#
+# where LYNX_ACTION is a key command specified as for lynx.cfg KEYMAP
+# options and as listed on the KEYMAP ('K') screen, and LYNX_EDITACTION
+# is a line-editor action specified as for KEYMAP and as listed in Line
+# Editor help pages. Using this form makes remapping according to user
+# preference with KEYMAP impossible, and should thus be used sparingly
+# (in general, use KEYMAP with PASS instead, if the goal is to force
+# recognition of a key in form text fields). For example:
+#
+#setkey "\033e" LAC:EDITTEXTAREA:PASS

+# Note that support for text & multipart are "built in" to metamail,
+# as are rudimentary support for message, and application.
+# However, any of these may be overridden in mailcap.
+#
+# Note that users may override or extend this with a .mailcap
+# file in their own directory. However, there is NO NEED
+# for them to copy entries from this file, as metamail will
+# pick up entries from both the system and personal mailcap files.
+#
+
+# NOTE: This file has been heavily modified for use as an example
+# configuration file for Lynx
+
+# In the samples given test=test -n "$DISPLAY" is used to
+# determine if the current session is X capable by checking
+# for the existence of a DISPLAY environment variable.
+# Lynx actually uses a getenv() call for DISPLAY (DECW$DISPLAY
+# on VMS) when it encounters test=test -n "$DISPLAY" or
+# test=test -z "$DISPLAY" in a viewer assignment, instead of
+# spawning to execute "test" via a system() call, i.e., those
+# two strings, respectively, are handled equivalently to the
+# :XWINDOWS and :NON_XWINDOWS flags for VIEWER: assignments
+# in lynx.cfg. Any system without the DISPLAY (or DECW$DISPLAY)
+# environment variable will be assumed to be Non-X.
+
+# You can append a ';' followed by "q=#.#", e.g., ; q=0.002
+# to set the quality parameter for the Content-Type, which can be
+# included in the Accept: header Lynx sends to http servers (the
+# default quality value is 1.0, and Lynx appends the parameter
+# to the Content-Type only if the value is less than 1.0).
+
+# You can append a ';' followed by "mxb=#", e.g., ; mxb=1000000
+# to set the maxbytes parameter for the Content-Type, which can be
+# included in the Accept: header Lynx sends to http servers (the
+# default maxbytes value is 0, meaning no maximum, and Lynx appends
+# the parameter to the Content-Type only if the value exceeds 0).
+
+# The following line is for sites where xv understands jpeg but xloadimage
+# is preferred.
+#
+# the test line specifies that this viewer should only be used if
+# the display variable is set.
+image/jpeg; xv %s; test=test -n "$DISPLAY"

+
+
+# If you have an interactive Postscript interpreter, you should think carefully

+# and should be uncommented if you DO have safe-tcl

+
+# A common problem with the mailcap mechanism is getting differential
+# behavior from different programs. This problem is compounded by the fact
+# that some programs, notably Mosaic, do not implement the "test" clause in
+# mailcap files. If you are using Lynx and X Mosaic together you should
+# place all X-centric entries before non-X entries. X Mosaic will use
+# whichever entry is defined first so further entries will be ignored.
+#
+# Lynx exports the environment variable LYNX_VERSION, so it can be tested
+# by scripts to determine if Lynx is running or not. However, the string
+# test=test -n "$LYNX_VERSION"
+# is handled simply as a flag which yields success when Lynx encounters it
+# in the mailcap file (i.e., Lynx does not bother to execute "test" via a
+# system() call to find out if it's running, because it obviously is).
+# Inclusion of the string for that test can be used to prevent other
+# software which reads the mailcap file from acting on assignments intended
+# only for Lynx. The string
+# test=test -z "$LYNX_VERSION"
+# similarly is treated by Lynx simply as a flag which yields failure.

+# Some scripts for handling mailto URLs within lynx via an interactive form
+#
+# Warning: this is a quick demo, to show what kinds of things are possible
+# by hooking some external commands into lynx. Use at your own risk.
+#
+# Requirements:
+#
+# - Perl and CGI.pm.
+# - A "sendmail" command for actually sending mail (if you need some
+# other interface, change the code below in sub sendit appropriately).
+# - Lynx compiled with support for lynxcgi, that means EXEC_CGI must have
+# been defined at compilation, usually done with
+# ./configure --enable-cgi-links
+# - Lynx must have support for CERN-style rules as of 2.8.3, which must
+# not have been disabled at compilation (it is enabled by default).
+#
+# Instructions:
+# (This is for people without lynxcgi experience; if you are already
+# use lynxcgi, you don't have to follow everything literally, use
+# common sense for picking appropriate file locations in your situation.)
+#
+# - Make a subdirectory 'lynxcgi' under you home directory, i.e.
+# mkdir ~/lynxcgi
+# - Put this three script file mailto-form.pl there and make it
+# executable. For example,
+# cp mailto-form.pl ~/lynxcgi
+# chmod a+x ~/lynxcgi/mailto-form.pl
+# - Edit mailto-form.pl (THIS FILE), there are some strings that
+# that need to be changed, see ### Configurable variables ###
+# below.
+# - Allow lynx to execute lynxcgi files in that directory, for example,
+# put in your lynx.cfg file:
+# TRUSTED_LYNXCGI:<tab>/home/myhomedir/lynxcgi/mailto-form.pl
+# where <tab> is a real TAB character and you have to put the real
+# location of your directory in place of "myhomedir", of course.
+# The '~' abbreviation cannot be used.
+# You could also just enable execution of all lynxcgi scripts, by
+# not having any TRUSTED_LYNXCGI options in lynx.cfg at all, but
+# that can't be recommended.
+# - Tell lynx to actually use the lynxcgi scripts for mailto URLs.
+# There are two variants:
+# a) Redirect "mailto"
+# Requires patched lynx, currently not yet in the developent code.
+# Use the following two lines in the file that is configured as
+# RULESFILE in lynxcfg:
+# PermitRedirection mailto:*
+# Redirect mailto:* lynxcgi:/home/myhomedir/lynxcgi/mailto-form.pl?from=myname@myhost&to=*
+# You can also put them directly in lynx.cfg, prefixing each with
+# "RULE:". Replace ""myhomedir", "myname", and "myhost" with your
+# correct values, of course.
+# b) Redirect "xmailto"
+# Requires defining a fake proxy before starting lynx, like
+# export xmailto_proxy=dummy # or for csh: setenv xmailto_proxy dummy
+# Requires that you change "mailto" to "xmailto" each time you want
+# to activate a mailto link. This can be done conveniently with
+# a few keys: 'E', ^A, 'x', Enter.
+# Use the following two lines in the file that is configured as
+# RULESFILE in lynxcfg:
+# PermitRedirection xmailto:*
+# Redirect xmailto:* lynxcgi:/home/myhomedir/lynxcgi/mailto-form.pl?from=myname@myhost&to=*
+# You can also put them directly in lynx.cfg, prefixing each with
+# "RULE:". Replace ""myhomedir", "myname", and "myhost" with your
+# correct values, of course.
+#
+# Limitations:
+#
+# - Only applies to mailto URLs that appear as links or are entered at
+# a 'g'oto prompt. Does not apply to other ways of sending mail, like
+# the 'c' (COMMENT) key, mailto as a FORM action, or mailing a file
+# from the 'P'rinting Options screen.
+# - Nothing is done for charset labelling, content-transfer-encoding
+# of non-ASCII characters, and other MIME niceties.

+# From: Vlad Harchev <hvv@hippo.ru>
+# Setting the normal and default types lets us keep (almost) the same colors
+# whether the terminal's default colors are white-on-black or black-on-white.
+# It is not exact since the default "white" is not necessarily the same color
+# as the ANSI lightgray, but is as close as we can get in a standard way.
+#
+# If you really want the terminal's default colors, and if lynx is built using
+# ncurses' default-color support, remove these two lines:
+normal: normal: lightgray:black
+default: normal: white:black
+
+# Notes:
+# better for eyes - it sets black background with mild colors that
+# have approximately the same intensity.
+#
+# grey normal text on black background with green links and brightgreen
+# highlighted links.
