       lynx - a general purpose distributed information browser for the World Wide Web


       lynx [options] [optional paths or URLs]

       lynx [options] [path or URL] -get_data

       lynx [options] [path or URL] -post_data

       Use “lynx -help” to display a complete list of current options.


       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.


       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.,


       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.

              apply restrictions for anonymous account, see also -restrictions.

              charset for documents that do not specify it.

              charset  assumed  for  local files, i.e., files which Lynx creates such as internal
              pages for the options menu.

              use this instead of unrecognized charsets.

              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.

              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.

              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.

              set the NUMBER of documents cached in memory.  The default is 10.

       -case  enable case-sensitive string searching.

              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”.

              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

              exit  on  left-arrow in startfile, but allow save to disk and associated print/mail

              write keystroke commands and related information to the specified file.

              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:

                 causes the script to stop, and forces Lynx to exit immediately.

                 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.

                 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.

              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.

              Sets the connection timeout, where N is given in seconds.

              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.

              specifies a file to use to store cookies.  If none is specified, the value given by
              -cookie_file is used.

              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.

              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.

              separate incremental display stages with MessageSecs delay

              toggles the default-colors feature which is normally set in the lynx.cfg file.

       -delay add DebugSecs delay after each progress-message

              set the display variable for X rexec-ed programs.

              set the charset for the terminal output.

              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

              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.

              enable external editing, using the specified EDITOR.  (vi, ed, emacs, etc.)

              enable emacs-like key movement.

              toggles  compatibility  with  communication  programs'  scrollback  keys  (may   be
              incompatible with some curses packages).

              define a file where Lynx will report HTTP access codes.

       -exec  enable local program execution (normally not configured).

              include all versions of files in local VMS directory listings.

              toggle  memory  leak-checking.  Normally this is not compiled-into your executable,
              but when it is, it can be disabled for a session.

              force HREF-less “A” elements to be empty (close them as soon as they are seen).

              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:

                  “.sht”, and

              toggles forcing of the secure flag for SSL cookies.

              toggles whether the Options Menu is key-based or form-based.

       -from  toggles transmissions of From headers.

       -ftp   disable ftp access.

              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.

              control the display of hidden links.

                 hidden  links  show up as bracketed numbers and are numbered together with other
                 links in the sequence of their occurrence in the document.

                 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.

                 hidden links do not appear even in listings.

              toggles use of “>” or “-->” as a terminator for comments.

              set homepage separate from start page.

              toggles inclusion of links for all images.

              set the default index file to the specified URL.

       -ismap toggles inclusion of ISMAP links when client-side MAPs are present.

              do justification of text.

              starting count for lnk#.dat files produced by -crawl.

              for -dump, show URL-encoded links decoded.

              for -dump, show the links inline with the text.

              for -dump, show only the list of links.

              disable URLs that point to remote hosts.

              enable local program execution from local files only (if  Lynx  was  compiled  with
              local execution enabled).

              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.

              prints the MIME header of a fetched document along with its source.

              toggles minimal versus valid comment parsing.

              toggles nested-tables logic (for debugging).

              number of articles in chunked news listings.

              maximum news articles in listings before chunking.

              disable bold video-attribute.

              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.

              force color mode off,  overriding  terminal  capabilities  and  any  -color  flags,
              COLORTERM variable, and saved .lynxrc settings.

              disable local program execution.  (DEFAULT)

              disable transmissions of Referer headers for file URLs.

              disable the link list feature in dumps.

       -nolog disable mailing of error messages to document owners.

              disable left/right margins in the default style sheet.

              disable -more- string in statusline messages.

              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.

              disable   link-   and   field-numbering.    This   overrides   -number_fields   and

              disable forced pauses for statusline messages.

              disable most print functions.

              prevents automatic redirection and prints a message with a link to the new URL.

              disable transmissions of Referer headers.

              disable reverse video-attribute.

              disable SOCKS proxy usage by a SOCKSified Lynx.

              disable the retrieval status messages.

              disable title and blank line from top of page.

              disable underline video-attribute.

              force numbering of links as well as form input fields

              force numbering of links.

              toggles display partial pages while loading.

              number of lines to render before repainting display with partial-display logic

              toggles passive ftp connections.

              set authorization ID and password for a protected proxy server at startup.  Be sure
              to protect any script files which use this switch.

       -popup toggles  handling  of single-choice SELECT options via popup windows or as lists of
              radio buttons.

              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.

              show  HTML  source  preparsed  and  reformatted when used with -source or in source

              show HTML source view with lexical elements and tags in color.

       -print enable print functions.  (default)

              toggles pseudo-ALTs for inline images with no ALT string.

       -raw   toggles default setting of 8-bit character translations or CJK mode for the startup
              character set.

       -realm restricts access to URLs in the starting realm.

              Sets the read-timeout, where N is given in seconds.

              flushes  the cache on a proxy server (only the first document given on the command-
              line is affected).

              allows a list of services to be disabled selectively.  Dashes  and  underscores  in
              option  names  can  be intermixed.  The following list is printed if no options are

                 restricts all options listed below.

                 disallow execution links via the bookmark file.

                 disallow changing the eXecute permission  on  files  (but  still  allow  it  for
                 directories) when local file management is enabled.

                 same as command line option -anonymous.  Disables default services for anonymous
                 users.  Set  to  all  restricted,  except  for:  inside_telnet,  outside_telnet,
                 inside_ftp,    outside_ftp,    inside_rlogin,    outside_rlogin,    inside_news,
                 outside_news, telnet_port, jump, mail, print, exec, and goto.  The settings  for
                 these, as well as additional goto restrictions for specific URL schemes that are
                 also applied, are derived from definitions within userdefs.h.

              resolutions but the one for URL itself,  will  be  redirected  through  the  SOCKS5
              proxy.    URL   may  be  given  as  “”,  “”,
              “”, or “” (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.

              toggles emulation of the old Netscape and Mosaic bug which treated  “>”  as  a  co-
              terminator for double-quotes and tags.

              works  the  same  as  dump  but outputs HTML source instead of formatted text.  For

                  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

              allow non-http startfile and homepage with -validate.

              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).

              disable recognition of telnet commands.

              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.)

              For win32, sets the network read-timeout, where N is given in seconds.

              emulator supports that escape code.  Has no effect when used with -notitle.

              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.

              enable  Waterloo  tcp/ip packet debug (print to watt debugfile).  This applies only
              to DOS versions compiled with WATTCP or WATT-32.

              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).

              emit backspaces in output if -dump'ing or -crawl'ing (like man does)

              tells  Lynx  that  it can ignore certain tags which have no content in an XHTML 1.0
              document.  For example “<p/>” will be discarded.


       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.


       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

                           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


                           See Lynx Users Guide for additional details and examples.

       SOCKS5_PROXY        Is  inspected  if  -socks5_proxy  has  not  been  used  (for  the same

       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

       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

       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

       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.


       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:














       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.


       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

       Lynx has incorporated code from a variety of sources along the way.  The earliest versions
       of  Lynx  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 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 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 Lynx's development  either  directly  (through  patches,  comments  or  bug
       reports) or indirectly (through inspiration and development of other systems).
