> Lynx Users Guide Version 2.5
>
> 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 PCs or Macs, or any other
> character-cell 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 and VMS.
>
> 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.

>Viewing local files with Lynx
>
> Lynx can be started by entering the Lynx command along with the name
> of a file to display. For example these commands could all be used to
> display an arbitrary ASCII text file.
>
> UNIX
> lynx myfile
> lynx /home/my-dir/myfile
>
> VMS
> lynx dua5:[my-directory]myfile
>
> When executed, Lynx will clear the screen and display as much of the
> specified file as will fit on the screen. Pressing a down-arrow will
> bring up the next screen, and pressing an up-arrow will bring up the
> previous screen. If no file is specified at startup, a default file
> will be displayed. (The default is configured by the system
> administrator when the command is installed.)
>
> Lynx will also display files written in the HyperText Markup Language
> (HTML), if the file's name ends with the characters ".html". HTML is a
> file format that allows users to create a file that contains (among
> other things) hypertext links to other files. Several files linked
> together may be described as a hypertext document.
>
> For example, these commands could be used to display files containing
> HTML hypertext:
>
> UNIX
> lynx myfile.html
> lynx /home/my-dir/myfile.html
>
> VMS
> lynx dua5:[me]myfile.html
>
> When Lynx displays an HTML file, it shows links as "bold face" text,
> except for one link, which is shown as "highlighted" text. Whether
> "boldface" or "highlighted" text shows up as reverse video, boldface
> type, or a color change, etc. depends on the display device being used
> (and the way in which that device has been configured). Lynx has no
> control over the exact presentation of links.
>
> The one link displayed as "highlighted" text is the currently
> "selected" link. Lynx will display the file associated with the
> selected link when a right-arrow or a Return key is pressed. To select
> a particular link, press the up-arrow or down-arrow keys until the
> desired link becomes "highlighted," and then press the right-arrow or
> Return key to view the linked information. Information included in the
> HTML file tells Lynx where to find the linked file and what kind of
> server will provide it (i.e. HTTP, Gopher, etc.).
>
> When a binary file is encountered Lynx will ask the user if he/she
> wishes to download the file or cancel. If the user selects 'D' for
> download, Lynx will transfer the file into a temporary location and
> present the user with a list of options. The only default option is
> "save file to disk", which is disabled if Lynx is running in anonymous
> mode. Any number of additional download methods may be defined in the
> lynx.cfg file by the system administrator. Programs like kermit,
> zmodem and FTP are some possible options. ToC
>
>Lynx online help
>
> Online help is available while viewing any document. Press the '?' or
> 'H' key to see a list of help topics. See the section titled
> 'Navigating hypertext documents with Lynx' for information on
> navigating through the help files. ToC
>
>Leaving Lynx
>
> To exit Lynx use the 'q' command. You will be asked whether you really
> want to quit. Answering 'y' will exit and 'n' will return you to the
> current document. Use 'Q' or CTRL-D to quit without verification. ToC
>
>Starting Lynx with a Remote File
>
> If you wish to view a remote file (that is, a file residing on some
> computer system other than the one upon which you are running Lynx)
> without first viewing a local file, you must identify that file by
> using a Uniform Resource Locator (URL). URL's take the general form:
>
> PROTOCOL :// HOST / PATH / FILENAME
>
> where
>
> PROTOCOL
> identifies the communications protocol used by the server that
> will provide the file. As mentioned earlier, Lynx (and any WWW
> client) can interact with a variety of servers, each with its
> own protocol.
>
> HOST
> is the Internet address of the computer system on which the
> server is running, and
>
> PATH and FILENAME
> identify the directory path and file of interest.
>
> Here are some sample URL's.
>
> HTTP (HyperText Transfer Protocol)
> http://www.nyu.edu/pages/wsn/subir/lynx.html
>
> Gopher
> gopher://gopher.micro.umn.edu/11/
>
> FTP (File Transfer Protocol)
> ftp://ftp2.cc.ukans.edu/pub/lynx/README
>
> WAIS (Wide Area Information Service protocol)
> wais://cnidr.org/directory-of-servers
>
> A URL may be specified to Lynx on the command line, as in:
>
>
> lynx http://kufacts.cc.ukans.edu/cwis/kufacts_start.html
>
> ToC
>
>Starting Lynx with the the WWW_HOME environment variable.
>
> You may also specify a starting file for Lynx using the WWW_HOME
> environment variable,
>
> UNIX
>
> ksh
> export WWW_HOME=http://www.w3.org/default.html
>
> csh
> setenv WWW_HOME http://www.w3.org/default.html
>
> VMS
> define "WWW_HOME" "http://www.w3.org/default.html";
>
>Navigating hypertext documents with Lynx
>
> The process of moving within a hypertext web, selecting and displaying
> links is known as "navigation." With Lynx almost all navigation can be
> accomplished with the arrow keys and the numeric keypad.
>
> +-------+-------+-------+
> | TOP | /|\ | Page |
> arrow keys | of | | | UP |
> | text 7| | 8| 9|
> +---------+ +-------+-------+-------+
> | SELECT | | | | |
> | prev /|\| | <--- | | ---> |

> |<-- prev | next | | sel. -->| | of | | | DOWN |
> | doc. | link \|/| link | | text 1| \|/ 2| 3|
> +---------+---------+---------+ +-------+-------+-------+
>
> There are also a few other keyboard commands to aid in navigation.
> Some of these commands depend on the fact that Lynx keeps a list of
> each file you visit called the "history list". The "backspace" or
> "delete" key will show you the whole history list. Any of the
> documents shown in the list may be revisited by selecting them from
> the history screen. The 'm' key command will take you back to the
> starting document unless you specified the -homepage=URL option at the
> command line.
>
> The 'i' key presents an index of documents. The default index is
> usually a document pointing to servers around the world, but the index
> can be changed by the system administrator or on the command line
> using the -index switch, and therefore depends on how the Lynx program
> you are using was configured.
>
> If you choose a link to a server with active access authorization Lynx
> will automatically prompt for a username and a password. If you give
> the correct information, you will then be served the requested
> information. Lynx will automatically send your username and password
> to the same server if it is needed again. ToC
>
>Printing, Mailing, and Saving files to disk.
>
> Documents may be printed using the 'p' command. After pressing the 'p'
> key a menu of Print Options will be displayed. The menu will vary
> according to several factors. First, some sites set up special
> accounts to let users run Lynx to access local information systems.
> Typically these accounts require no passwords and do not require users
> to identify themselves. As a result such accounts are called
> "anonymous" accounts, and their users are considered "anonymous"
> users. In most configurations, all Lynx users (including anonymous
> users) are able to mail files to themselves and print the entire file
> to the screen.
>
> Additional print options are available for users who are using Lynx
> from their own accounts (that is, so-called "non-anonymous users"). In
> particular, the "Save to a local file" option allows you to save the
> document into a file on your disk space. Any number of additional
> print options may also be available as configured by your system
> administrator. ToC
>
>Lynx searching commands
>
> Two commands activate searching in Lynx: "/" and "s". While viewing a
> normal document use the "/" command to find a word or phrase within
> the current document. The search type will depend on the search option
> setting in the options menu (see below). The search options are case
> sensitive and case insensitive. Some documents are designated "index
> documents". These documents can be searched to retrieve additional
> information from an index server. The "s" key allows searching of
> index documents. ToC
>
>Lynx options menu
>
> The Lynx Options Menu may be accessed by pressing the 'o' key. The
> current Lynx Options Menu contains the following configurable options.
>
> Options Menu
>
> E)ditor : emacs
> D)ISPLAY variable : aixtest.cc.ukans.edu:0.0
> B)ookmark file : home_page
> F)TP sort criteria : By Filename
> P)ersonal mail address : address@hidden
> S)earching type : CASE INSENSITIVE
> display (C)haracter set : ISO Latin 1
> V)I keys : OFF
> e(M)acs keys : OFF
> K)eypad as arrows
> or Numbered links : Numbers act as arrows
> preferred document lan(G)uage: en
> preferred document c(H)arset : NONE
> l(I)st directory style : Mixed style
> sho(W) dot files : OFF
> U)ser mode : Advanced
> user (A)gent : [User-Agent header]
> L)ocal execution links : Always off
>
> An option can be changed by entering the capital letter of the option
> you want to change (i.e. 'E' for Editor). For fields where text must
> be entered, simply enter the text by typing on the keyboard. The
> Backspace and Delete keys can be used to correct mistakes, and CTRL-U
> can be used to erase the whole line. When you are done entering a
> change press the Return key to get back to the Command? prompt.
>
> For fields where you must choose from a list of choices, press any key
> to toggle the choices and press the Return key to finish the change.
>
> When you are done changing options use the 'r' command to return to
> Lynx or the '>' command to save the options to a .lynxrc file and
> return to Lynx.
>
> The following table describes the options available on the Options
> Menu:
>
> Editor
> The editor to be invoked when editing browsable files, and
> sending mail or comments. The full pathname of the editor
> command should be specified when possible.
>
> DISPLAY variable
> This option is only available on UNIX systems and is only
> relevant to X Window users. The DISPLAY variable is picked up
> automatically from the environment if it has been previously
> set.
>
> Bookmark file
> This is the filename and location of your personal bookmark
> file. The bookmark file allows frequently travelled links to be
> stored in a personal easy to access file. Using the 'a' command
> (see below) you may save any link into your bookmark file. If
> the path specified does not begin with a slash then the path
> will reference your home directory.
>
> FTP sort criteria
> This option allows you to specify how files will be sorted
> within FTP listings. The current options include "By Filename",
> "By Size", "By Type", and "By Date".
>
> Personal mail address
> This mail address will be used to help you send files to
> yourself and will be included as the From: address in any mail
> or comments that you send. It will also be sent as the From:
> field in all HTTP get requests.
>
> Searching type
> Searching type has two possible values: CASE INSENSITIVE
> (default) and CASE SENSITIVE. The searching type effects
> inter-document searches only, and determines whether searches
> for words within documents will be done in a case-sensitive or
> case-insensitive manner.
>
> Display Character set
> This option allows you to set up the default character set for
> your specific terminal. The character set provides a mapping of
> 8 bit ISO Latin character entities into viewable characters and
> is only important if you will be viewing these type of
> characters with Lynx.
>
> VI keys
> If set to ON then the lowercase h,j,k, and l keys will be
> mapped to left, down, up, and right arrow, respectively.
>
> Emacs keys
> If set to ON then the CTRL-P, CTRL-N, CTRL-F, and CTRL-B keys
> will be mapped to up, down, right, and left arro arrow arroww,
> respectively.
>
> Keypad as arrows or numbered links
> This option gives the choice between navigating with the arrow
> keys or having every link numbered so that the links may be
> selected by numbers as well as using the arrow keys.
>
> Preferred Document Language
> The language you prefer if multi-language files are available
> from servers. Use MIME abbreviations, e.g., en for English, fr
> for French, etc. Can be a comma-separated list in descending
> order of preferences.
>
> Preferred Document Charset
> The character set you prefer if sets in addition to ISO-8859-1
> and US-ASCII are available from servers. Use MIME notation
> (e.g., ISO-8859-2) and do not include ISO-8859-1 or US-ASCII,
> since those values are always assumed by default. Can be a
> comma-separated list in descending order of preferences.
>
> List directory style
> Applies to Directory Editing. Files and directories can be
> presented in the following ways:
>
> Mixed style
> Files and directories are listed together in alphabetical
> order.
>
> Directories first
> Files and directories are separated into two alphabetical
> lists. Directories are listed first.
>
> Files first
> Files and directories are separated into two alphabetical
> lists. Files are listed first.
>
> Show dot files
> If display/creation of hidden (dot) files/directories is
> enabled, you can turn the feature on or off via this setting.
>
> User Mode
> There are three possible choices: Novice, Intermediate, and
> Advanced.
>
> Novice
> In Novice mode two lines of help are displayed at the
> bottom of the screen.
>
> Intermediate
> Intermediate mode turns off the help lines.
>
> Advanced
> Advanced mode displays the URL of the currently selected
> link at the bottom of the screen.
>
> User Agent
> The header string which Lynx sends to servers to indicate the
> User-Agent is displayed here. It cannot be changed. Users often
> request ability to change it so that they can indicate other
> agents to servers which return different documents based on the
> User-Agent. Netscape Communications Corp. has indicated that it
> considers false transmissions of "Mozilla" as the User-Agent to
> be a copyright infringement, which will be prosecuted.
>
> Local execution scripts or links
> Local execution can be activated by the system administrator.
> If it has not been activated you will not see this option in
> the options menu. When a local execution script is encountered
> Lynx checks the users options to see whether the script can be
> executed. Users have the following options:
>
> Always off
> Local execution scripts will never be executed
>
> For Local files only
> Local execution scripts will only be executed if the
> script to be executed resides on the local machine, and
> is referenced by a URL that begins with
> "file://localhost"
>
> Always on
> All local exection scripts will be executed
>
>
> If the users options permit the script to be executed Lynx will
> spawn a shell and run the script. If the script cannot be
> executed Lynx will show the script within the Lynx window and
> inform the user that the script is not allowed to be executed
> and will ask the user to check his/her options. ToC
>
>Comments and mailto: links
>
> At any time while viewing documents within Lynx, you may use the 'c'
> command to send a mail message to the owner of the current document if
> the author of the document has specified ownership. If no ownership is
> specified then comments are disabled. Certain links called "mailto:";
> links will also allow you to send mail to other people. Using the mail
> features within Lynx is straightforward.
>
> Once you have decided to send a comment or have selected a "mailto:";
> link a new screen will appear showing you who you are sending the
> message to. Lynx will ask for your name, your e-mail address, and the
> subject of the message. If you have filled in the "personal mail
> address" field in the Options Menu, your e-mail address will be filled
> in automatically. After entering the above information, if you have an
> editor defined in the Options Menu and you are not an anonymous user
> then your specified editor will be spawned for you so that you can
> enter your message. If you do not have an editor defined or you are an
> anonymous user, a simple line mode input scheme will allow you to
> enter your message.
>
> To finish sending the message, exit your spawned editor or, if you are
> using the simple line mode input scheme, type a "." (period) on a line
> by itself. You will be asked a final time whether to send the message.
> If you press 'y' then the message will be sent, if you press 'n' the
> message will be deleted. ToC
>
>USENET News posting
>
> While reading news articles with Lynx you should see a link that says
> "Reply to address@hidden" and a link that says "Reply to newsgroup(s)"
>
> Reply to address@hidden
> address@hidden will actually appear as the mail address of the
> person who posted the news article. Selecting the link will
> allow you to send a message to the person who wrote the message
> you are currently viewing. You will be given the option of
> including the original message in your reply.
>
> Reply to newsgroup(s)
> Selecting this link will allow you to post back to the
> newsgroup that you are currently reading and any newsgroups
> that the message may be cross-posted to. You will be given the
> option of including the original message in your reply. Once
> you have typed in your message the inews program will be called
> to post your message to your news host. ToC
>
>Lynx and HTML Forms
>
> This section describes the Lynx Forms Interface. HTML gives document
> providers the ability to create on-line forms which may be filled out
> when the document is viewed. When a form is submitted the information
> on the form can be used to search a database or complete a survey.
>
> An HTML Form provides for the use of buttons or to perform an action
> (such as submit), checkboxes and radio buttons to select options from
> a list, and fields for entering text.
>
> Buttons:
> Buttons are displayed in the same way that Lynx displays links
> in a document. To "push" the button press the RIGHT ARROW or
> RETURN key.
>
> Checkboxes and Radio buttons
> Checkboxes and radio buttons are displayed as parenthesis: ().
> When a box is checked or a button selected, an asterisk appears
> within the parenthesis: (*). To check a box or select a radio
> button press the RIGHT ARROW or RETURN key.
>
> Selection Fields
> Selection fields are displayed as brackets with the default
> option displayed between them: [default__]. To select an option
> press theRIGHT ARROW or RETURN key. A box with a border of
> asterisks will appear with the list of possible options listed
> within the box. Use the UP ARROW and DOWN ARROW keys to move
> the cursor between options and the RIGHT ARROW or RETURN key to
> select an option.
>
> Text Entry Fields
> Text entry fields are displayed as a row of underscores the
> length of the entry field: _______. You may enter text directly
> by typing at the keyboard. Use the BACKSPACE key to correct
> errors. If you input more text than the field can hold your
> input will be truncated. If you fill a text field the cursor
> will not move off the field but remain at the last field
> position.
>
> You can move around the form using the standard Lynx navigation keys.
> UP ARROW and DOWN ARROW keys respectively select the previous or next
> field, box, or button. The TAB key selects the next field, box, or
> button.
>
> NOTE: If you have a text input field selected you will not have access
> to any of the Lynx keystroke commands. Select a button or box when you
> want to use Lynx keystrokes.
>
>Viewing the HTML document source and editing documents
>
> When viewing HTML documents it is possible to view the unrendered
> (i.e., the original HTML) source of the document by pressing the '\'
> (backslash) key. The document will be reloaded from the server or disk
> and displayed on the screen unrendered. When viewing unrendered
> documents you may print them as any normal document.
>
> Selecting the Print to a local file option from the Print Menu, makes
> it possible to save the source of the document to disk so that you may
> have a local copy of the document.
>
> NOTE: When saving an HTML document it is important to name the
> document with a ".html" extension, if you want to read it with Lynx
> again later.
>
> Lynx can allow users to edit documents that reside on the local
> system. To enable editing, documents must be referenced using a
> "file:" URL or by specifying a plain filename on the command line as
> in the following two examples:
>
>
> lynx file://localhost/FULL/PATH/FILENAME
> lynx path/filename.html
>
> In addition, the user must also specify an editor in the Options Menu
> so that Lynx knows which editor to use. If the file is specified
> correctly and an editor is defined, then you may edit documents by
> using the 'e' command. When the 'e' command is entered your specified
> editor is spawned to edit the file. After changes are completed, exit
> your editor and you will return to Lynx. Lynx will reload and render
> the file so that changes can be immediately examined. ToC
>
>Reloading files and refreshing the display
>
> The CTRL-R command will reload and rerender the file that you are
> currently viewing. CTRL-L or CTRL-W will refresh or wipe the screen to
> remove or correct any errors that may be caused by operating system or
> other messages. ToC
>
>Lynx bookmarks
>
> It is often useful to place a bookmark to aid in returning quickly to
> a document. To use the bookmark feature you must first use the Options
> Menu to specify a bookmark filename.
>
> To save a bookmark to the document you wish to place in the bookmark
> file press the 'a' key and you will be asked
>
>
> Save D)ocument or L)ink to bookmark file or C)ancel? (d,l,c):
>
> Answer 'd' to save a link to the document you are currently viewing or
> 'l' to save the link that is currently selected on the page. Selecting
> 'c' will cancel without saveing anything to your bookmark file.
>
> Use the 'v' command to view the list of bookmarks you have saved.
> While viewing the bookmark list you may select a bookmark as you would
> any other link. ToC
>
>Jump Command
>
> A feature similar to the Lynx bookmarks is the jump command. The jump
> command allows you to enter a shortcut name to access a URL. If the
> jump feature is active, typing 'j' will produce a prompt where you may
> enter the shortcut name. Type '?' at the jump prompt for a list of
> shortcut names available.
>
> Note to System Administrators: Read the "lynx.cfg" file on how to set
> up the jump command for your system and how to define shortcut names.
> ToC
>
>Directory Editing
>
> A new feature in lynx is DIRED support. When a local directory is
> accessed using a URL of the form file://localhost/path/, a new set of
> commands is available. With DIRED support you can create, edit,
> delete, copy, and move files on your local system. The commands
> available in DIRED mode are
>
> C)reate
> Type 'c' to create a new file. New file will be empty.
>
> D)ownload
> Type 'd' to download selection using one of the options defined
> by your system administrator.
>
> E)dit
> Type 'e' to spawn the editor defined in options menu and load
> selected file for editing.
>
> F)ull Menu
> Type 'f' to show full menu of options available for selection.
> Menu may vary according to type of file selected and
> compression facilities available.
>
> M)odify
> Type 'm' to modify the name or location of file. Then type 'n'
> to rename the file or 'l' to move the file to a different
> location.
>
> R)emove
> Type 'r' to remove the selected file or directory.
>
> T)ag
> Type 't' to tag highlighted file. Further operations will be
> performed on tagged files instead of highlighted ones.
>
> U)pload
> Type 'u' to upload a file to the present directory. Upload
> methods are defined by your system administrator.
>
> ToC
>
>Other useful commands
>
> !
> When '!' is pressed your default shell will be spawned. When
> you quit or exit the shell you will return to Lynx. (Usually
> 'exit' under UNIX and 'logout' under VMS) This command is
> usually disabled for anonymous users.
>
> g
> The 'g' command allows any URL to be viewed. Pressing the 'g'
> command will bring up a prompt asking for a URL. Type in the
> URL that you wish to view.
>
> =
> The '=' command shows information about the current document
> and the currently selected link if there is one. The number of
> lines in the file, URL, title, owner, and type are shown.
>
> ^T
> Control-T toggles trace mode on and off. This is useful for
> diagnosing bad html. If you get a BAD HTML statusline message
> when loading a document, enter Control-T and then Control-R to
> reload the document in trace mode. If you are able to diagnose
> the problem, send a message about it to the document's author.
>
> *
> The '*' command toggles image_links mode on and off. When on,
> links will be created for all images, including inlines. If you
> have an image viewer mapped to the image's MIME type, you can
> activate such links to view an inline image. You should
> normally have this mode toggled off.
>
> [
> The '[' command toggles pseudo_inlines mode on and off. When
> on, inline images which have no ALT string specified will have
> an "[INLINE]" pseudo-ALT string inserted in the Lynx display.
> When off, they will be treated as having ALT="" (i.e., they'll
> be ignored). If image_links mode is toggled on, the pseudo-ALT
> strings will be restored, to serve as links to the inline
> images' sources.
>
> ]
> The ']' command is used to send HEAD requests for the current
> document or link. It applies only to documents or links (or
> form submit buttons) of http servers. A statusline message will
> notify you if the context for this command was inappropriate.
> The HEAD requests always are sent to the http server, i.e.,
> Lynx does not retrieve any previous server replies from its
> cache. Note that for form submissions, http servers vary in
> whether they'll treat HEAD requests as valid and return the CGI
> script's headers, or treat it as invalid and return an error
> message.
>
> #
> The '#' command jumps you to the pseudo Toolbar or Banner if
> present in the current document. Use Left-Arrow to return from
> there to your previous position in the document.
>
> z
> Lynx supports completely interruptable I/O processes. Press the
> 'z' key at any time during a connect or transfer process and
> the process will be halted. If any data was transferred before
> the interrupt, it will be displayed. ToC
>
>The Lynx command
>
> The basic syntax of the Lynx command can be represented as one of the
> following:
>
>
> lynx [options]
> lynx [options] startup_file
>
> where
>
> startup_file
> is the file that Lynx will load at start-up.
>

>Lynx development history
>
> Lynx grew out of efforts to build a campus-wide information system at
> The University of Kansas. The earliest versions of Lynx provided a
> user-friendly, distributed hypertext interface for users connected to
> multiuser (UN*X and VMS) systems via curses-oriented display devices.
> A custom hypertext format was developed to support hypertext links to
> local files and files on remote Gopher servers. Using Gopher servers
> for distributed file service allowed information providers to publish
> information from a wide variety of platforms (including UN*X, VMS,
> VM/CMS and Macintosh). In addition, Lynx became the most user-friendly
> Gopher client, although that was only an ancillary capability.
>
> This distributed approach let providers retain complete control over
> their information, but it made communication between users and
> providers somewhat more difficult. Following the lead of Neal Erdwien,
> of Kansas State University, the Lynx hypertext format was extended to
> include links for including ownership information with each file. This
> information made it possible for users running Lynx clients to send
> comments and suggestions via e-mail to the providers.
>
> This early version of Lynx was also augmented to support hypertext
> links to programs running on remote systems. It included the ability
> to open a Telnet connection, as well as the ability to start programs
> via rexec, inetd, or by direct socket connects. These capabilities
> were included to allow users to access databases or custom program
> interfaces.
>
> A subsequent version of Lynx incorporated the World Wide Web libraries
> to allow access to the full list of WWW servers, along with the option
> to build hypertext documents in HTML, rather than the native Lynx
> format. HTML has become far more widely used, and the native format
> has been phased out. With the addition of the WWW libraries, Lynx
> became a fully-featured WWW client, limited only by the display
> capabilites offered in the curses environment.
>
> Lynx was designed by Lou Montulli, Charles Rezac and Michael Grobe of
> Academic Computing Services at The University of Kansas. Lynx was
> implemented by Lou Montulli and maintained by Garrett Arch Blythe and
> Craig Lavender.
>
> Foteos Macrides and members of the lynx-dev list have developed and
> supported Lynx since release of v2.3 in May 1994. The Lynx2-3-FM code
> set was released as v2.4 in June 1995, and the Lynx2-4-FM code set was
> released as v2.5 in May 1996.
>
> 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 UN*X environment. Those versions also incorporated
> libraries from the UN*X 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 others) and the WWW
> community.
>
> Information on obtaining the most current version of Lynx is available
> via the Lynx Enhanced Pages.
