Environment Settings Relevant to BitchX                                   

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 BitchX is no
exception.  The following variables are used by BitchX:

   IRCPORT     default server port to connect to
   IRCUMODE    initial user mode (does not work on all servers)
   IRCPATH     same as LOAD_PATH setting
   IRCRC       alternate startup file (in lieu of ~/.ircrc)

                     to get a list of servers from

login to your Unix system.  All environment variables are available for
