+Use \*(``lynx \-help\*('' to display a complete list of current options.
+.SH DESCRIPTION
+.hy 0
+.I
+Lynx
+is a fully-featured World Wide Web (WWW) client for users
+running cursor-addressable, character-cell display devices
+(e.g., vt100 terminals,
+vt100 emulators running on Windows or any POSIX platform,
+or any other \*(``curses-oriented\*('' display).
+It will display hypertext
+markup language (HTML) documents containing links to
+files residing on the local system, as well as files residing on
+remote systems running Gopher, HTTP, FTP, WAIS, and NNTP servers.
+.PP
+.I
+Lynx
+has been ported to many systems,
+including all variants of Unix,
+Windows (since Windows 95),
+DOS DJGPP and OS/2,
+as well as VMS and OS/390.
+.PP
+.I
+Lynx
+can be used to access information on the World Wide Web, or
+to build information systems intended primarily for local access.
+For example,
+.I
+Lynx
+has been used to build several Campus Wide
+Information Systems (CWIS).
+In addition,
+.I
+Lynx
+can be used to
+build systems isolated within a single LAN.
+.SH OPTIONS
+At start up, \fILynx\fR will load any local
+file or remote URL specified at the command line.
+For help with URLs, press \*(``\fB?\fR\*(''
+or \*(``\fBH\fR\*('' while running \fILynx\fR.
+Then follow the link titled, \*(``Help on URLs.\*(''
+.PP
+If more than one local file or remote URL is listed on the command line,
+\fILynx\fP will open only the last interactively.
+All of the names (local files and remote URLs)
+are added to the \fBG)oto\fP history.
+.PP
+\fILynx\fR uses only long option names.
+Option names can begin with double dash \*(``\-\-\*('' as well,
+underscores and dashes can be intermixed in
+option names (in the reference below, options
+are shown
+with one dash \*(``\-\*('' before them, and
+with underscores \*(``_\*('').
+.PP
+\fILynx\fR provides many command-line options.
+Some options require a value (string, number or keyword).
+These are noted in the reference below.
+The other options set boolean values in the program.
+There are three types of boolean options: set, unset and toggle.
+If no option value is given, these have the obvious meaning:
+set (to true), unset (to false), or toggle (between true/false).
+For any of these, an explicit value can be given in different
+forms to allow for operating system constraints,
+e.g.,
+.NS
+\fB\-center:off\fP
+\fB\-center=off\fP
+\fB\-center\-\fP
+.NE
+.PP
+\fILynx\fR recognizes
+\*(``1\*('', \*(``+\*('', \*(``on\*('' and \*(``true\*('' for true values, and
+\*(``0\*('', \*(``\-\*('', \*(``off\*('' and \*(``false\*('' for false values.
+Other option-values are ignored.
+.PP
+The default boolean, number and string option values that are compiled
+into \fILynx\fP are displayed in the help-message provided by \fBlynx \-help\fP.
+Some of those may differ according to how \fILynx\fP was built;
+see the help message itself for these values.
+The \fB\-help\fP option is processed in the third pass of options-processing,
+so any option which sets a value,
+as well as runtime configuration values are reflected in the help-message.
+.TP 7
+.B \-
+If the argument is only \*(``\-\*('', then \fILynx\fP expects to receive
+the arguments from the standard input.
+This is to allow for the
+potentially very long command line that can be associated
+with the \fB\-get_data\fR or \fB\-post_data\fR arguments (see below).
+It can also be used to avoid having sensitive information
+in the invoking command line (which would be visible to
+other processes on most systems), especially when
+the \fB\-auth\fR or \fB\-pauth\fR options are used.
+.TP
+.B \-accept_all_cookies
+accept all cookies.
+.TP
+.B \-anonymous
+apply restrictions for anonymous account, see also \fB\-restrictions\fR.
+.TP
+.B \-assume_charset\fR=\fIMIMEname
+charset for documents that do not specify it.
+.TP
+.B \-assume_local_charset\fR=\fIMIMEname
+charset assumed for local files,
+i.e., files which \fILynx\fP creates such as
+internal pages for the options menu.
+.TP
+.B \-assume_unrec_charset\fR=\fIMIMEname
+use this instead of unrecognized charsets.
+.TP
+.B \-auth\fR=\fIID\fR:\fIPASSWD
+set authorization ID and password for protected documents at startup.
+Be sure to protect any script files which use
+this switch.
+.TP
+.B \-base
+prepend a request URL comment and BASE tag to text/html
+outputs for \fB\-source\fR dumps.
+.TP
+.B \-bibhost\fR=\fIURL
+specify a local bibp server (default http://bibhost/).
+.TP
+.B \-blink
+forces high intensity background colors for color mode, if available
+and supported by the terminal.
+This applies to the \fBslang\fR library (for a few terminal emulators),
+or to OS/2 EMX with \fBncurses\fR.
+.TP
+.B \-book
+use the bookmark page as the startfile.
+The default or command
+line startfile is still set for the Main screen command, and will
+be used if the bookmark page is unavailable or blank.
+.TP
+.B \-buried_news
+toggles scanning of news articles for buried references, and
+converts them to news links.
+Not recommended because email
+addresses enclosed in angle brackets will be converted to
+false news links, and uuencoded messages can be trashed.
+.TP
+.B \-cache\fR=\fINUMBER
+set the NUMBER of documents cached in memory.
+The default is 10.
+.TP
+.B \-case
+enable case-sensitive string searching.
+.TP
+.B \-center
+toggles center alignment in HTML TABLE.
+Normally table cells are centered on the table grid.
+Set this option \*(``on\*('' to disable centering.
+The default is \*(``off\*(''.
+.TP
+.B \-cfg\fR=\fIFILENAME
+specifies a \fILynx\fP configuration file other than the default
+lynx.cfg.
+.TP
+.B \-child
+exit on left-arrow in startfile, and disable save to disk and associated
+print/mail options.
+.TP
+.B \-child_relaxed
+exit on left-arrow in startfile, but allow save to disk and associated
+print/mail options.
+.TP
+.B \-cmd_log\fR=\fIFILENAME
+write keystroke commands and related information to the specified file.
+.TP
+.B \-cmd_script\fR=\fIFILENAME
+read keystroke commands from the specified file.
+You can use the data written using the \fB\-cmd_log\fR option.
+\fILynx\fP will ignore other information which the command-logging may have
+written to the logfile.
+Each line of the command script contains either
+a comment beginning with \*(``#\*('',
+or a keyword:
+.RS
+.TP 3
+.B exit
+causes the script to stop, and forces \fILynx\fP to exit immediately.
+.TP
+.B key
+the character value, in printable form.
+Cursor and other special keys are given as names, e.g., \*(``Down Arrow\*(''.
+Printable 7-bit ASCII codes are given as-is,
+and hexadecimal values represent other 8-bit codes.
+.TP
+.B set
+followed by a \*(``name=value\*('' allows one to override values set in the
+lynx.cfg or \&.lynxrc files.
+\fILynx\fP tries the cfg-file setting first.
+.RE
+.TP
+.B \-collapse_br_tags
+toggles collapsing of BR tags.
+.TP
+.B \-color
+forces color mode on, if available.
+Default color control sequences
+which work for many terminal types are assumed if the terminal
+capability description does not specify how to handle color.
+\fILynx\fP needs to be compiled with the \fBslang\fR library for this flag,
+it is equivalent to setting the \fBCOLORTERM\fR environment variable.
+(If color support is instead provided by a color-capable curses
+library like \fBncurses\fR, \fILynx\fP relies completely on the terminal
+description to determine whether color mode is possible, and
+this flag is not needed and thus unavailable.)
+A saved show_color=always setting found in a \&.lynxrc file at
+startup has the same effect.
+A saved show_color=never found
+in \&.lynxrc on startup is overridden by this flag.
+.TP
+.B \-connect_timeout\fR=\fIN
+Sets the connection timeout, where N is given in seconds.
+.TP
+.B \-cookie_file\fR=\fIFILENAME
+specifies a file to use to read cookies.
+If none is specified, the default value is \s+3~\s-3/.lynx_cookies
+for most systems, but \s+3~\s-3/cookies for MS-DOS.
+.TP
+.B \-cookie_save_file\fR=\fIFILENAME
+specifies a file to use to store cookies.
+If none is specified, the value given by
+\fB\-cookie_file\fR is used.
+.TP
+.B \-cookies
+toggles handling of Set-Cookie headers.
+.TP
+.B \-core
+toggles forced core dumps on fatal errors.
+Turn this option off to ask \fILynx\fP to force
+a core dump if a fatal error occurs.
+.TP
+.B \-crawl
+with \fB\-traversal,\fR output each page to a file.
+with \fB\-dump\fR, format output as with \fB\-traversal\fR,
+but to the standard output.
+.TP
+.B \-curses_pads
+toggles the use of curses \*(``pad\*('' feature which supports
+left/right scrolling of the display.
+The feature is normally available for curses configurations,
+but inactive.
+To activate it, use the \*(``|\*('' character or the LINEWRAP_TOGGLE command.
+Toggling this option makes the feature altogether unavailable.
+.TP
+.B \-debug_partial
+separate incremental display stages with MessageSecs delay
+.TP
+.B \-default_colors
+toggles the default-colors feature which is normally set in the lynx.cfg file.
+.TP
+.B \-delay
+add DebugSecs delay after each progress-message
+.TP
+.B \-display\fR=\fIDISPLAY
+set the display variable for X rexec-ed programs.
+.TP
+.B \-display_charset\fR=\fIMIMEname
+set the charset for the terminal output.
+.TP
+.B \-dont_wrap_pre
+inhibit wrapping of text when \fB\-dump\fR'ing and \fB\-crawl\fR'ing,
+mark wrapped lines of <pre> in interactive session.
+.TP
+.B \-dump
+dumps the formatted output of the default document or those
+specified on the command line to standard output.
+Unlike interactive mode, all documents are processed.
+This can be used in the following way:
+.NS
+lynx \fB\-dump\fR http://www.subir.com/lynx.html
+.NE
+.IP
+Files specified on the command line are formatted as HTML if
+their names end with one of the standard web suffixes such
+as \*(``.htm\*('' or \*(``.html\*(''.
+Use the \fB\-force_html\fP option to format files whose names do not follow
+this convention.
+.TP
+.B \-editor\fR=\fIEDITOR
+enable external editing, using the specified
+EDITOR.
+(vi, ed, emacs, etc.)
+.TP
+.B \-emacskeys
+enable emacs-like key movement.
+.TP
+.B \-enable_scrollback
+toggles compatibility with communication programs' scrollback keys
+(may be incompatible with some curses packages).

+force HREF-less \*(``A\*('' elements to be empty
+(close them as soon as they are seen).
+.TP
+.B \-force_html
+forces the first document to be interpreted as HTML.
+.IP
+This is most useful when processing files specified on the command line
+which have an unrecognized suffix (or the suffix is associated with a
+non-HTML type, such as \*(``.txt\*('' for plain text files).
+.IP
+\fILynx\fP recognizes these file suffixes as HTML:
+.NS
+\*(``.ht3\*('',
+\*(``.htm\*('',
+\*(``.html3\*('',
+\*(``.html\*('',
+\*(``.htmlx\*('',
+\*(``.php3\*('',
+\*(``.php\*('',
+\*(``.phtml\*('',

+hidden links show up as bracketed numbers
+and are numbered together with other links in the sequence of their
+occurrence in the document.
+.TP
+.B listonly
+hidden links are shown only on \fBL)ist\fP screens and listings generated by
+.B \-dump
+or from the \fBP)rint\fP menu, but appear separately at the end of those lists.
+This is the default behavior.
+.TP
+.B ignore
+hidden links do not appear even in listings.
+.RE
+.TP
+.B \-historical
+toggles use of \*(``>\*('' or \*(``\-\->\*('' as a terminator for comments.

+Here are some of the most useful:
+.bP
+Use \fBUp arrow\fR and \fBDown arrow\fR to scroll through hypertext links.
+.bP
+\fBRight arrow\fR or \fBReturn\fR will follow a highlighted hypertext link.
+.bP
+\fBLeft Arrow\fR or \*(``\fBu\fR\*('' will retreat from a link.
+.bP
+Type \*(``\fBH\fR\*('', \*(``\fB?\fR\*('', or \fBF1\fR
+for online help and descriptions of key-stroke commands.
+.bP
+Type \*(``\fBk\fR\*('' or \*(``\fBK\fR\*('' for a list of the current key-stroke
+command mappings.
+.IP
+If the same command is mapped to the same letter differing only

+.bP
+Type \fBDelete\fR to view history list.
+.SH ENVIRONMENT
+In addition to various \*(``standard\*('' environment variables such as
+\fBDISPLAY\fR,
+\fBHOME\fR,
+\fBPATH\fR,
+\fBSHELL\fR,
+\fBTMPDIR\fR,
+\fBUSER\fR,
+etc.,
+\fILynx\fR utilizes several \fILynx\fP-specific environment variables, if they
+exist.
+.PP
+Others may be created or modified by \fILynx\fR to pass data to an external
+program, or for other reasons.
+These are listed separately below.
+.PP
+See also the sections on \fBSIMULATED CGI SUPPORT\fR and
+\fBNATIVE LANGUAGE SUPPORT\fR, below.
+.PP
+Note:  Not all environment variables apply to all types of platforms
+supported by \fILynx\fR, though most do.
+Feedback on platform dependencies is solicited.
+.PP
+Environment Variables Used By \fILynx\fR:
+.TP 20
+.B COLORTERM
+If set, color capability for the terminal is forced on at startup time.
+The actual value assigned to the variable is ignored.
+This variable is only meaningful if \fILynx\fR was built using the \fBslang\fR
+screen-handling library.
+.TP
+.B LYNX_CFG
+This variable, if set, will override the default location and name of
+the global configuration file (normally, \fBlynx.cfg\fR) that was defined
+by the LYNX_CFG_FILE constant in the userdefs.h file, during installation.
+.IP
+See the userdefs.h file for more information.
+.TP
+.B LYNX_CFG_PATH
+If set, this variable overrides the compiled-in search-list of directories
+used to find the configuration files, e.g., \fBlynx.cfg\fP and \fBlynx.lss\fP.
+The list is delimited with ":" (or ";" for Windows) like the \fBPATH\fP
+environment variable.

+character style sheet file.
+[Currently only meaningful if \fILynx\fR was
+built using curses color style support.]
+.TP
+.B LYNX_SAVE_SPACE
+This variable, if set, will override the default path prefix for files
+saved to disk that is defined in the \fBlynx.cfg SAVE_SPACE:\fR statement.
+.IP
+See the \fBlynx.cfg\fR file for more information.
+.TP
+.B LYNX_TEMP_SPACE
+This variable, if set, will override the default path prefix for temporary
+files that was defined during installation, as well as any value that may
+be assigned to the \fBTMPDIR\fR variable.
+.TP
+.B MAIL
+This variable specifies the default inbox \fILynx\fR will check for new
+mail, if such checking is enabled in the \fBlynx.cfg\fR file.
+.TP
+.B NEWS_ORGANIZATION
+This variable, if set, provides the string used in the \fBOrganization:\fR
+header of \fBUSENET\fR news postings.
+It will override the setting of the
+ORGANIZATION environment variable, if it is also set (and, on \fBUNIX\fR,
+the contents of an /etc/organization file, if present).
+.TP
+.B NNTPSERVER
+If set, this variable specifies the default NNTP server that will be used
+for \fBUSENET\fR news reading and posting with \fILynx\fR, via news: URL's.
+.TP
+.B ORGANIZATION
+This variable, if set, provides the string used in the \fBOrganization:\fR
+header of \fBUSENET\fR news postings.
+On \fBUNIX\fR, it will override the
+contents of an /etc/organization file, if present.

+.I PROTOCOL\fB_proxy\fR
+\fILynx\fR supports the use of proxy servers that can act as firewall
+gateways and caching servers.
+They are preferable to the older gateway
+servers (see WWW_access_GATEWAY, below).
+.IP
+Each protocol used by \fILynx\fR,
+(http, ftp, gopher, etc), can be mapped separately by setting environment
+variables of the form \fIPROTOCOL\fP_proxy.
+Protocols are indicated in a URI by the name before \*(``:\*('', e.g.,
+\*(``http\*('' in
+\*(``http://some.server.dom:port/\*('' for HTML.
+.IP
+Depending on your system configuration and supported protocols,
+the environment variables recognized by \fIlynx\fP may include
+.NS
+cso_proxy
+finger_proxy
+ftp_proxy
+gopher_proxy
+http_proxy
+https_proxy
+news_proxy
+newspost_proxy

+.TP
+.B SSL_CERT_DIR
+Set to the directory containing trusted certificates.
+.TP
+.B SSL_CERT_FILE
+Set to the full path and filename for your file of trusted certificates.
+.TP
+.B WWW_\fIaccess\fB_GATEWAY
+\fILynx\fR still supports use of gateway servers, with the servers specified
+via \*(``WWW_\fIaccess\fP_GATEWAY\*('' variables
+(where \*(``\fIaccess\fP\*('' is lower case and can be
+\*(``http\*('', \*(``ftp\*('', \*(``gopher\*('' or \*(``wais\*('').
+However most gateway servers have been discontinued.
+Note that you do not include a terminal \*(``/\*('' for gateways, but
+do for proxies specified by \fIPROTOCOL\fP_proxy environment variables.
+.IP
+See \fBLynx Users Guide\fR for details.
+.TP
+.B WWW_HOME
+This variable, if set, will override the default startup URL specified
+in any of the \fILynx\fR configuration files.

+(the latter on the DOS/Windows platforms).
+The trace file is in either case relative to the home directory.
+.TP
+.B LYNX_VERSION
+This variable is always set by \fILynx\fR, and may be used by an external
+program to determine if it was invoked by \fILynx\fR.
+.IP
+See also the comments
+in the distribution's sample \fBmailcap\fR file, for notes on usage in such
+a file.
+.TP
+.B TERM
+Normally, this variable is used by \fILynx\fR to determine the terminal type
+being used to invoke \fILynx\fR.
+If, however, it is unset at startup time
+(or has the value \*(``unknown\*(''),
+or if the \fB\-term\fR command-line option is used (see \fBOPTIONS\fR section
+above), \fILynx\fR will set or modify its value to the user specified
+terminal type (for the \fILynx\fR execution environment).
+Note: If set/modified by \fILynx\fR, the values of the \fBLINES\fR and/or
+\fBCOLUMNS\fR environment variables may also be changed.
+.SS "Simulated CGI Support"
+If built with the \fBcgi-links\fR option enabled, \fILynx\fR allows access
+to a cgi script directly without the need for an http daemon.
+.PP
+When executing such \*(``lynxcgi scripts\*('' (if enabled),
+the following variables may be set for simulating a CGI environment:
+.PP
+.B CONTENT_LENGTH
+.PP
+.B CONTENT_TYPE

+.PP
+.B QUERY_STRING
+.PP
+.B REMOTE_ADDR
+.PP
+.B REMOTE_HOST
+.PP
+.B REQUEST_METHOD
+.PP
+.B SERVER_SOFTWARE
+.PP
+Other environment variables are not inherited by the script, unless they
+are provided via a LYNXCGI_ENVIRONMENT statement in the configuration file.
+See the \fBlynx.cfg\fR file, and the (draft) CGI 1.1 Specification
+<http://Web.Golux.Com/coar/cgi/draft\-coar\-cgi\-v11\-00.txt> for the
+definition and usage of these variables.
+.PP
+The CGI Specification, and other associated documentation, should be consulted
+for general information on CGI script programming.
+.SS "Native Language Support"
+If configured and installed with \fBNative Language Support\fR, \fILynx\fR
+will display status and other messages in your local language.
+See the
+file \fBABOUT_NLS\fR in the source distribution, or at your local \fBGNU\fR
+site, for more information about internationalization.
+.PP
+The following environment variables may be used to alter default settings:
+.TP 20
+.B LANG
+This variable, if set, will override the default message language.
+It is an \fBISO 639\fR two-letter code identifying the language.
+Language codes are \fBNOT\fR the same
+as the country codes given in \fBISO 3166\fR.
+.TP

+.SS Acknowledgments
+\fILynx\fP has incorporated code from a variety of sources along the way.
+The earliest versions of \fILynx\fP included code from Earl Fogel of Computing
+Services at the University of Saskatchewan, who implemented HYPERREZ
+in the Unix environment.
+HYPERREZ was developed by Niel Larson of
+Think.com and served as the model for the early versions of \fILynx\fP.
+Those versions also incorporated libraries from the Unix Gopher clients
+developed at the University of Minnesota, and the later versions of
+\fILynx\fP rely on the WWW client library code developed by Tim Berners-Lee
+and the WWW community.
+Also a special thanks to Foteos Macrides who ported
+much of \fILynx\fP to VMS and did or organized most of its development since the
+departures of Lou Montulli and Garrett Blythe from the University of Kansas
+in the summer of 1994 through the release of v2.7.2, and to everyone
+on the net who has contributed to \fILynx\fP's development either directly
+(through patches, comments or bug reports) or indirectly
+(through inspiration and development of other systems).
