+
+2 Description
+ 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 95/NT/XP/7/8 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. Current
+ versions of Lynx run on Unix, VMS, Windows 95/NT/XP/7/8, DOS DJGPP and
+ OS/2.
+
+ Lynx can be used to access information on the World Wide Web, or to
+ build information systems intended primarily for local access. For
+ example, Lynx has been used to build several Campus Wide Information
+ Systems (CWIS). In addition, Lynx can be used to build systems
+ isolated within a single LAN.
+
+2 Options
+ At start up, Lynx will load any local file or remote URL specified at
+ the command line. For help with URLs, press "?" or "H" while running
+ Lynx. Then follow the link titled, "Help on URLs."
+
+ If more than one local file or remote URL is listed on the command
+ line, Lynx will open only the last interactively. All of the names
+ (local files and remote URLs) are added to the G)oto history.
+
+ Lynx 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 "_").
+
+ Lynx 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.,
+
+ -center:off
+ -center=off
+ -center-
+
+ Lynx recognizes "1", "+", "on" and "true" for true values, and "0",
+ "-", "off" and "false" for false values. Other option-values are
+ ignored.
+
+ The default boolean, number and string option values that are compiled
+ into Lynx are displayed in the help-message provided by lynx -help.
+ Some of those may differ according to how Lynx was built; see the help
+ message itself for these values. The -help 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.
+
+ - If the argument is only "-", then Lynx 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 -get_data or -post_data 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 -auth or -pauth options are used.
+
+ -accept_all_cookies
+ accept all cookies.
+
+ -anonymous
+ apply restrictions for anonymous account, see also
+ -restrictions.
+
+ -assume_charset=MIMEname
+ charset for documents that do not specify it.
+
+ -assume_local_charset=MIMEname
+ charset assumed for local files, i.e., files which Lynx creates
+ such as internal pages for the options menu.
+
+ -assume_unrec_charset=MIMEname
+ use this instead of unrecognized charsets.
+
+ -auth=ID:PASSWD
+ set authorization ID and password for protected documents at
+ startup. Be sure to protect any script files which use this
+ switch.
+
+ -base prepend a request URL comment and BASE tag to text/html outputs
+ for -source dumps.
+
+ -bibhost=URL
+ specify a local bibp server (default http://bibhost/).
+
+ -blink forces high intensity background colors for color mode, if
+ available and supported by the terminal. This applies to the
+ slang library (for a few terminal emulators), or to OS/2 EMX
+ with ncurses.
+
+ -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.
+
+ -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.
+
+ -cache=NUMBER
+ set the NUMBER of documents cached in memory. The default is
+ 10.
+
+ -case enable case-sensitive string searching.
+
+ -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".
+
+ -cfg=FILENAME
+ specifies a Lynx configuration file other than the default
+ lynx.cfg.
+
+ -child exit on left-arrow in startfile, and disable save to disk and
+ associated print/mail options.
+
+ -child_relaxed
+ exit on left-arrow in startfile, but allow save to disk and
+ associated print/mail options.
+
+ -cmd_log=FILENAME
+ write keystroke commands and related information to the
+ specified file.
+
+ -cmd_script=FILENAME
+ read keystroke commands from the specified file. You can use
+ the data written using the -cmd_log option. Lynx 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:
+
+ exit
+ causes the script to stop, and forces Lynx to exit
+ immediately.
+
+ 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.
+
+ set
+ followed by a "name=value" allows one to override values set
+ in the lynx.cfg or .lynxrc files. Lynx tries the cfg-file
+ setting first.
+
+ -collapse_br_tags
+ toggles collapsing of BR tags.
+
+ -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. Lynx needs to be compiled with the slang library for
+ this flag, it is equivalent to setting the COLORTERM environment
+ variable. (If color support is instead provided by a color-
+ capable curses library like ncurses, Lynx 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.
+
+ -connect_timeout=N
+ Sets the connection timeout, where N is given in seconds.
+
+ -cookie_file=FILENAME
+ specifies a file to use to read cookies. If none is specified,
+ the default value is ~/.lynx_cookies for most systems, but
+ ~/cookies for MS-DOS.
+
+ -cookie_save_file=FILENAME
+ specifies a file to use to store cookies. If none is specified,
+ the value given by -cookie_file is used.
+
+ -cookies
+ toggles handling of Set-Cookie headers.
+
+ -core toggles forced core dumps on fatal errors. Turn this option off
+ to ask Lynx to force a core dump if a fatal error occurs.
+
+ -crawl with -traversal, output each page to a file. with -dump, format
+ output as with -traversal, but to the standard output.
+
+ -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.
+
+ -debug_partial
+ separate incremental display stages with MessageSecs delay
+
+ -default_colors
+ toggles the default-colors feature which is normally set in the
+ lynx.cfg file.
+
+ -delay add DebugSecs delay after each progress-message
+
+ -display=DISPLAY
+ set the display variable for X rexec-ed programs.
+
+ -display_charset=MIMEname
+ set the charset for the terminal output.
+
+ -dont_wrap_pre
+ inhibit wrapping of text when -dump'ing and -crawl'ing, mark
+ wrapped lines of <pre> in interactive session.
+
+ -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:
+
+ lynx -dump http://www.subir.com/lynx.html
+
+ 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 -force_html option to format files
+ whose names do not follow this convention.
+
+ -editor=EDITOR
+ enable external editing, using the specified EDITOR. (vi, ed,
+ emacs, etc.)
+
+ -emacskeys
+ enable emacs-like key movement.
+
+ -enable_scrollback
+ toggles compatibility with communication programs' scrollback
+ keys (may be incompatible with some curses packages).
+
+ -error_file=FILE
+ define a file where Lynx will report HTTP access codes.
+
+ -exec enable local program execution (normally not configured).
+
+ -fileversions
+ include all versions of files in local VMS directory listings.
+
+ -find_leaks
+ toggle memory leak-checking. Normally this is not compiled-into
+ your executable, but when it is, it can be disabled for a
+ session.
+
+ -force_empty_hrefless_a
+ force HREF-less "A" elements to be empty (close them as soon as
+ they are seen).
+
+ -force_html
+ forces the first document to be interpreted as HTML.
+
+ 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).
+
+ Lynx recognizes these file suffixes as HTML:
+
+ ".ht3",
+ ".htm",
+ ".html3",
+ ".html",
+ ".htmlx",
+ ".php3",
+ ".php",
+ ".phtml",
+ ".sht", and
+ ".shtml".
+
+ -force_secure
+ toggles forcing of the secure flag for SSL cookies.
+
+ -forms_options
+ toggles whether the Options Menu is key-based or form-based.
+
+ -from toggles transmissions of From headers.
+
+ -ftp disable ftp access.
+
+ -get_data
+ properly formatted data for a get form are read in from the
+ standard input and passed to the form. Input is terminated by a
+ line that starts with "---".
+
+ Lynx issues an HTTP GET, sending the form to the path or URL
+ given on the command-line and prints the response of the server.
+ If no path or URL is given, Lynx sends the form to the start-
+ page.
+
+ -head send a HEAD request for the mime headers.
+
+ -help print the Lynx command syntax usage message, and exit.
+
+ -hiddenlinks=[option]
+ control the display of hidden links.
+
+ merge
+ hidden links show up as bracketed numbers and are numbered
+ together with other links in the sequence of their occurrence
+ in the document.
+
+ listonly
+ hidden links are shown only on L)ist screens and listings
+ generated by -dump or from the P)rint menu, but appear
+ separately at the end of those lists. This is the default
+ behavior.
+
+ ignore
+ hidden links do not appear even in listings.
+
+ -historical
+ toggles use of ">" or "-->" as a terminator for comments.
+
+ -homepage=URL
+ set homepage separate from start page.
+
+ -image_links
+ toggles inclusion of links for all images.
+
+ -index=URL
+ set the default index file to the specified URL.
+
+ -ismap toggles inclusion of ISMAP links when client-side MAPs are
+ present.
+
+ -justify
+ do justification of text.

+ -link=NUMBER
+ starting count for lnk#.dat files produced by -crawl.
+
+ -list_decoded
+ for -dump, show URL-encoded links decoded.
+

+
+ -listonly
+ for -dump, show only the list of links.
+
+ -localhost
+ disable URLs that point to remote hosts.
+
+ -locexec
+ enable local program execution from local files only (if Lynx
+ was compiled with local execution enabled).
+
+ -lss=FILENAME
+ specify filename containing color-style information. The
+ default is lynx.lss. If you give an empty filename, Lynx uses a
+ built-in monochrome scheme which imitates the non-color-style
+ configuration.
+
+ -mime_header
+ prints the MIME header of a fetched document along with its
+ source.
+
+ -minimal
+ toggles minimal versus valid comment parsing.
+
+ -nested_tables
+ toggles nested-tables logic (for debugging).
+
+ -newschunksize=NUMBER
+ number of articles in chunked news listings.
+
+ -newsmaxchunk=NUMBER
+ maximum news articles in listings before chunking.
+
+ -nobold
+ disable bold video-attribute.
+
+ -nobrowse
+ disable directory browsing.
+
+ -nocc disable Cc: prompts for self copies of mailings. Note that this
+ does not disable any CCs which are incorporated within a mailto
+ URL or form ACTION.
+
+ -nocolor
+ force color mode off, overriding terminal capabilities and any
+ -color flags, COLORTERM variable, and saved .lynxrc settings.
+
+ -noexec
+ disable local program execution. (DEFAULT)

+ disable left/right margins in the default style sheet.
+
+ -nomore
+ disable -more- string in statusline messages.
+
+ -nonrestarting_sigwinch
+ This flag is not available on all systems, Lynx needs to be
+ compiled with HAVE_SIGACTION defined. If available, this flag
+ may cause Lynx to react more immediately to window changes when
+ run within an xterm.
+
+ -nonumbers
+ disable link- and field-numbering. This overrides
+ -number_fields and -number_links.
+
+ -nopause
+ disable forced pauses for statusline messages.
+
+ -noprint
+ disable most print functions.
+
+ -noredir
+ prevents automatic redirection and prints a message with a link

+ switch.
+
+ -popup toggles handling of single-choice SELECT options via popup
+ windows or as lists of radio buttons.
+
+ -post_data
+ properly formatted data for a post form are read in from the
+ standard input and passed to the form. Input is terminated by a
+ line that starts with "---".
+
+ Lynx issues an HTTP POST, sending the form to the path or URL
+ given on the command-line and prints the response of the server.
+ If no path or URL is given, Lynx sends the form to the start-
+ page.
+
+ -preparsed
+ show HTML source preparsed and reformatted when used with
+ -source or in source view.
+
+ -prettysrc

+ resumes session from specified file.
+
+ -sessionout=FILENAME
+ saves session to specified file.
+
+ -short_url

+
+ -show_cfg
+ Print the configuration settings, e.g., as read from "lynx.cfg",
+ and exit.
+
+ -show_cursor
+ If enabled the cursor will not be hidden in the right hand
+ corner but will instead be positioned at the start of the
+ currently selected link. Show cursor is the default for systems
+ without FANCY_CURSES capabilities. The default configuration
+ can be changed in userdefs.h or lynx.cfg. The command line

+ "192.168.0.1:1080" (and IPv6 notation if so supported). A
+ SOCKS5 proxy may also be specified via the environment variable
+ SOCKS5_PROXY. This option controls the builtin SOCKS5 support,
+ which is unrelated to the option -nosocks.
+
+ -soft_dquotes
+ toggles emulation of the old Netscape and Mosaic bug which
+ treated ">" as a co-terminator for double-quotes and tags.
+
+ -source
+ works the same as dump but outputs HTML source instead of
+ formatted text. For example
+
+ lynx -source . >foo.html
+
+ generates HTML source listing the files in the current
+ directory. Each file is marked by an HREF relative to the
+ parent directory. Add a trailing slash to make the HREF's
+ relative to the current directory:
+
+ lynx -source ./ >foo.html
+
+ -stack_dump
+ disable SIGINT cleanup handler
+
+ -startfile_ok
+ allow non-http startfile and homepage with -validate.
+
+ -stderr
+ When dumping a document using -dump or -source, Lynx normally
+ does not display alert (error) messages that you see on the
+ screen in the status line. Use the -stderr option to tell Lynx
+ to write these messages to the standard error.
+
+ -stdin read the startfile from standard input (UNIX only).
+
+ -syslog=text
+ information for syslog call.
+
+ -syslog_urls
+ log requested URLs with syslog.
+
+ -tagsoup
+ initialize parser, using Tag Soup DTD rather than SortaSGML.
+
+ -telnet
+ disable recognition of telnet commands.
+
+ -term=TERM
+ tell Lynx what terminal type to assume it is talking to. (This
+ may be useful for remote execution, when, for example, Lynx
+ connects to a remote TCP/IP port that starts a script that, in
+ turn, starts another Lynx process.)
+
+ -timeout=N
+ For win32, sets the network read-timeout, where N is given in
+ seconds.
+
+ -tlog toggles between using a Lynx Trace Log and stderr for trace
+ output from the session.
+
+ -tna turns on "Textfields Need Activation" mode.
+
+ -trace turns on Lynx trace mode. Destination of trace output depends
+ on -tlog.
+
+ -trace_mask=value
+ turn on optional traces, which may result in very large trace
+ files. Logically OR the values to combine options:
+
+ 1 SGML character parsing states
+
+ 2 color-style
+
+ 4 TRST (table layout)
+
+ 8 configuration (lynx.cfg, .lynxrc, .lynx-keymaps, mime.types
+ and mailcap contents)
+
+ 16 binary string copy/append, used in form data construction.
+
+ 32 cookies
+
+ 64 character sets
+
+ 128
+ GridText parsing
+
+ 256
+ timing
+
+ 512
+ detailed URL parsing
+
+ -traversal
+ traverse all http links derived from startfile. When used with
+ -crawl, each link that begins with the same string as startfile
+ is output to a file, intended for indexing.
+
+ See CRAWL.announce for more information.
+
+ -trim_blank_lines
+ toggles trimming of trailing blank lines as well as the related
+ trimming of blank lines while collapsing BR tags.
+
+ -trim_input_fields
+ trim input text/textarea fields in forms.
+
+ -underline_links
+ toggles use of underline/bold attribute for links.
+
+ -underscore
+ toggles use of _underline_ format in dumps.
+
+ -unique_urls
+ check for duplicate link numbers in each page and corresponding
+ lists, and reuse the original link number.
+
+ -update_term_title
+ enables updating the title in terminal emulators. Use only if
+ your terminal emulator supports that escape code. Has no effect
+ when used with -notitle.
+
+ -use_mouse
+ turn on mouse support, if available. Clicking the left mouse
+ button on a link traverses it. Clicking the right mouse button
+ pops back. Click on the top line to scroll up. Click on the
+ bottom line to scroll down. The first few positions in the top
+ and bottom line may invoke additional functions. Lynx must be
+ compiled with ncurses or slang to support this feature. If
+ ncurses is used, clicking the middle mouse button pops up a
+ simple menu. Mouse clicks may only work reliably while Lynx is
+ idle waiting for input.
+
+ -useragent=Name
+ set alternate Lynx User-Agent header.
+
+ -validate
+ accept only http URLs (for validation). Complete security
+ restrictions also are implemented.
+
+ -verbose
+ toggle [LINK], [IMAGE] and [INLINE] comments with filenames of
+ these images.
+
+ -version
+ print version information, and exit.
+
+ -vikeys
+ enable vi-like key movement.
+
+ -wdebug
+ enable Waterloo tcp/ip packet debug (print to watt debugfile).
+ This applies only to DOS versions compiled with WATTCP or
+ WATT-32.
+
+ -width=NUMBER
+ number of columns for formatting of dumps, default is 80. This
+ is limited by the number of columns that Lynx could display,
+ typically 1024 (the MAX_LINE symbol).
+
+ -with_backspaces
+ emit backspaces in output if -dump'ing or -crawl'ing (like man
+ does)
+
+ -xhtml_parsing
+ tells Lynx that it can ignore certain tags which have no content
+ in an XHTML 1.0 document. For example "<p/>" will be discarded.
+
+2 Commands
+ More than one key can be mapped to a given command. Here are some of
+ the most useful:
+
+ * Use Up arrow and Down arrow to scroll through hypertext links.
+
+ * Right arrow or Return will follow a highlighted hypertext link.
+
+ * Left Arrow or "u" will retreat from a link.
+
+ * Type "H", "?", or F1 for online help and descriptions of key-stroke
+ commands.
+
+ * Type "k" or "K" for a list of the current key-stroke command
+ mappings.
+
+ If the same command is mapped to the same letter differing only by
+ upper/lowercase only the lowercase mapping is shown.
+
+ * Type Delete to view history list.
+
+2 Environment
+ In addition to various "standard" environment variables such as HOME,
+ PATH, USER, DISPLAY, TMPDIR, etc, Lynx utilizes several Lynx-specific
+ environment variables, if they exist.
+
+ Others may be created or modified by Lynx to pass data to an external
+ program, or for other reasons. These are listed separately below.
+
+ See also the sections on SIMULATED CGI SUPPORT and NATIVE LANGUAGE
+ SUPPORT, below.
+
+ Note: Not all environment variables apply to all types of platforms
+ supported by Lynx, though most do. Feedback on platform dependencies
+ is solicited.
+
+ Environment Variables Used By Lynx:
+
+ 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 Lynx was built using the slang
+ screen-handling library.
+
+ LYNX_CFG This variable, if set, will override the default
+ location and name of the global configuration file
+ (normally, lynx.cfg) that was defined by the
+ LYNX_CFG_FILE constant in the userdefs.h file,
+ during installation.
+
+ See the userdefs.h file for more information.
+
+ LYNX_CFG_PATH If set, this variable overrides the compiled-in
+ search-list of directories used to find the
+ configuration files, e.g., lynx.cfg and lynx.lss.
+ The list is delimited with ":" (or ";" for Windows)
+ like the PATH environment variable.
+
+ LYNX_HELPFILE If set, this variable overrides the compiled-in URL
+ and configuration file URL for the Lynx help file.
+
+ LYNX_LOCALEDIR If set, this variable overrides the compiled-in
+ location of the locale directory which contains
+ native language (NLS) message text.
+
+ LYNX_LSS This variable, if set, specifies the location of
+ the default Lynx character style sheet file.
+ [Currently only meaningful if Lynx was built using
+ curses color style support.]
+
+ LYNX_SAVE_SPACE This variable, if set, will override the default
+ path prefix for files saved to disk that is defined
+ in the lynx.cfg SAVE_SPACE: statement.
+
+ See the lynx.cfg file for more information.
+
+ 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 TMPDIR variable.
+
+ MAIL This variable specifies the default inbox Lynx will
+ check for new mail, if such checking is enabled in
+ the lynx.cfg file.
+
+ NEWS_ORGANIZATION This variable, if set, provides the string used in
+ the Organization: header of USENET news postings.
+ It will override the setting of the ORGANIZATION
+ environment variable, if it is also set (and, on
+ UNIX, the contents of an /etc/organization file, if
+ present).
+
+ NNTPSERVER If set, this variable specifies the default NNTP
+ server that will be used for USENET news reading
+ and posting with Lynx, via news: URL's.
+
+ ORGANIZATION This variable, if set, provides the string used in
+ the Organization: header of USENET news postings.
+ On UNIX, it will override the contents of an
+ /etc/organization file, if present.
+
+ PROTOCOL_proxy Lynx 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).
+
+ Each protocol used by Lynx, (http, ftp, gopher,
+ etc), can be mapped separately by setting
+ environment variables of the form PROTOCOL_proxy.
+ Protocols are indicated in a URI by the name before
+ ":", e.g., "http" in "http://some.server.dom:port/"
+ for HTML.
+
+ Depending on your system configuration and
+ supported protocols, the environment variables
+ recognized by lynx may include
+
+ cso_proxy
+ finger_proxy
+ ftp_proxy
+ gopher_proxy
+ https_proxy
+ http_proxy
+ newspost_proxy
+ newsreply_proxy
+ news_proxy
+ nntp_proxy
+ no_proxy
+ snewspost_proxy
+ snewsreply_proxy
+ snews_proxy
+ wais_proxy
+
+ See Lynx Users Guide for additional details and
+ examples.
+
+ SOCKS5_PROXY Is inspected if -socks5_proxy has not been used
+ (for the same content).
+
+ SSL_CERT_DIR Set to the directory containing trusted
+ certificates.
+
+ SSL_CERT_FILE Set to the full path and filename for your file of
+ trusted certificates.
+
+ WWW_access_GATEWAY Lynx still supports use of gateway servers, with
+ the servers specified via "WWW_access_GATEWAY"
+ variables (where "access" 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 PROTOCOL_proxy
+ environment variables.
+
+ See Lynx Users Guide for details.
+
+ WWW_HOME This variable, if set, will override the default
+ startup URL specified in any of the Lynx
+ configuration files.
+
+ Environment Variables Set or Modified By Lynx:
+
+ LYNX_PRINT_DATE This variable is set by the Lynx p(rint) function,
+ to the Date: string seen in the document's
+ "Information about" page (= cmd), if any. It is
+ created for use by an external program, as defined
+ in a lynx.cfg PRINTER: definition statement. If
+ the field does not exist for the document, the
+ variable is set to a null string under UNIX, or "No
+ Date" under VMS.
+
+ LYNX_PRINT_LASTMOD This variable is set by the Lynx p(rint) function,
+ to the Last Mod: string seen in the document's
+ "Information about" page (= cmd), if any. It is
+ created for use by an external program, as defined
+ in a lynx.cfg PRINTER: definition statement. If
+ the field does not exist for the document, the
+ variable is set to a null string under UNIX, or "No
+ LastMod" under VMS.
+
+ LYNX_PRINT_TITLE This variable is set by the Lynx p(rint) function,
+ to the Linkname: string seen in the document's
+ "Information about" page (= cmd), if any. It is
+ created for use by an external program, as defined
+ in a lynx.cfg PRINTER: definition statement. If
+ the field does not exist for the document, the
+ variable is set to a null string under UNIX, or "No
+ Title" under VMS.
+
+ LYNX_PRINT_URL This variable is set by the Lynx p(rint) function,
+ to the URL: string seen in the document's
+ "Information about" page (= cmd), if any. It is
+ created for use by an external program, as defined
+ in a lynx.cfg PRINTER: definition statement. If
+ the field does not exist for the document, the
+ variable is set to a null string under UNIX, or "No
+ URL" under VMS.
+
+ LYNX_TRACE If set, causes Lynx to write a trace file as if the
+ -trace option were supplied.
+
+ LYNX_TRACE_FILE If set, overrides the compiled-in name of the trace
+ file, which is either Lynx.trace or LY-TRACE.LOG
+ (the latter on the DOS/Windows platforms). The
+ trace file is in either case relative to the home
+ directory.
+
+ LYNX_VERSION This variable is always set by Lynx, and may be
+ used by an external program to determine if it was
+ invoked by Lynx.
+
+ See also the comments in the distribution's sample
+ mailcap file, for notes on usage in such a file.
+
+ TERM Normally, this variable is used by Lynx to
+ determine the terminal type being used to invoke
+ Lynx. If, however, it is unset at startup time (or
+ has the value "unknown"), or if the -term command-
+ line option is used (see OPTIONS section above),
+ Lynx will set or modify its value to the user
+ specified terminal type (for the Lynx execution
+ environment). Note: If set/modified by Lynx, the
+ values of the LINES and/or COLUMNS environment
+ variables may also be changed.
+
+2 Simulated Cgi Support
+ If built with the cgi-links option enabled, Lynx allows access to a cgi
+ script directly without the need for an http daemon.
+
+ When executing such "lynxcgi scripts" (if enabled), the following
+ variables may be set for simulating a CGI environment:
+
+ CONTENT_LENGTH
+
+ CONTENT_TYPE
+
+ DOCUMENT_ROOT
+
+ HTTP_ACCEPT_CHARSET
+
+ HTTP_ACCEPT_LANGUAGE
+
+ HTTP_USER_AGENT
+
+ PATH_INFO
+
+ PATH_TRANSLATED
+
+ QUERY_STRING
+
+ REMOTE_ADDR
+
+ REMOTE_HOST
+
+ REQUEST_METHOD
+
+ SERVER_SOFTWARE
+
+ Other environment variables are not inherited by the script, unless
+ they are provided via a LYNXCGI_ENVIRONMENT statement in the
+ configuration file. See the lynx.cfg 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.
+
+ The CGI Specification, and other associated documentation, should be
+ consulted for general information on CGI script programming.
+
+2 Native Language Support
+ If configured and installed with Native Language Support, Lynx will
+ display status and other messages in your local language. See the file
+ ABOUT_NLS in the source distribution, or at your local GNU site, for
+ more information about internationalization.
+
+ The following environment variables may be used to alter default
+ settings:
+
+ LANG This variable, if set, will override the default
+ message language. It is an ISO 639 two-letter code
+ identifying the language. Language codes are NOT
+ the same as the country codes given in ISO 3166.
+
+ LANGUAGE This variable, if set, will override the default
+ message language. This is a GNU extension that has
+ higher priority for setting the message catalog
+ than LANG or LC_ALL.
+
+ LC_ALL and
+
+ LC_MESSAGES These variables, if set, specify the notion of
+ native language formatting style. They are POSIXly
+ correct.
+
+ LINGUAS This variable, if set prior to configuration,
+ limits the installed languages to specific values.
+ It is a space-separated list of two-letter codes.
+ Currently, it is hard-coded to a wish list.
+
+ NLSPATH This variable, if set, is used as the path prefix
+ for message catalogs.

+
+2 Acknowledgments
+ Lynx has incorporated code from a variety of sources along the way.
+ The earliest versions of Lynx included code from Earl Fogel of Comput-
+ ing Services at the University of Saskatchewan, who implemented HYPER-
+ REZ in the Unix environment. HYPERREZ was developed by Niel Larson of
+ Think.com and served as the model for the early versions of Lynx.
+ Those versions also incorporated libraries from the Unix Gopher clients
+ developed at the University of Minnesota, and the later versions of
+ Lynx 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 Lynx to VMS and did or organized most of its development
+ since the departures of Lou Montulli and Garrett Blythe from the Uni-
+ versity of Kansas in the summer of 1994 through the release of v2.7.2,
+ and to everyone on the net who has contributed to Lynx's development
+ either directly (through patches, comments or bug reports) or indirect-
+ ly (through inspiration and development of other systems).
