+======Environment Settings Relevant to EPIC======
+Numerous environment variables are recognized by .  Environment variables are
+various settings that describe your login process on a Unix system.  How they
+are set mainly depends on the command shell you use.
+  * For csh and tcsh shells: \\ setenv variable "value"
+  * For bash, ksh, and zsh shells: \\ export variable="value"
+  * For sh (a true Bourne shell) and ash shells, and Bourne-like shells: \\ variable="value" \\ export variable
+  * For the rc and es shells (Plan 9 descendants): \\ variable='value'
+For all shells (except rc and es), either single quotes (') or double quotes
+(") may be used.  For all shells, the case of the variable is significant.
+Environment variables are, by convention, in all uppercase, and EPIC is no
+exception.  The following variables are used by EPIC:
+|IRCNICK           |default nickname when connecting to a server                                          |
+|IRCNAME           |any lunacy you want instead of your real name                                         |
+|IRCHOST           |default local host name to use on multihomed hosts                                    |
+|IRCSERVER         |default server list, space delimited, serv:port:pass ok                               |
+|IRCPORT           |default server port to connect to                                                     |
+|IRCUMODE          |initial user mode (does not work on all servers)                                      |
+|IRCPATH           |same as [[set LOAD_PATH|LOAD_PATH]] setting                                           |
+|IRCRC             |alternate startup file (in lieu of ~/.ircrc)                                          |
+|IRC_SERVERS_FILE  |same as compile-time SERVERS_FILE, specifies a file to get a list of servers from     |
+EPIC also uses the TERM and HOME variables, which are usually set when you
+login to your Unix system.  All environment variables are available for use
+inside EPIC as normal variables, assuming another variable of the same name
+does not exist.
