====== Crossfire Server Environment Variables ======

The crossfire [[:server]] recognizes the following environmental variables; \\
these should correspond to their [[positional parameters]] counterparts, and be overridden by those.

  * CROSSFIRE_**LIBDIR**  //-data// ( **/absolute/**path/to/share/crossfire //directory// )
  * CROSSFIRE_**LOCALDIR** //-localdir// ( **/absolute/**path/to/var/crossfire //directory// )
  * CROSSFIRE_PLAYERDIR //-playerdir// ( relative/path/to/players //dir// inside **LOCALDIR** directory )
  * CROSSFIRE_MAPDIR    //-maps// ( relative/path/to/maps //dir// inside **LIBDIR** directory )
  * CROSSFIRE_ARCHETYPES //-arch// ( relative/path/to/archetypes //file// inside **LIBDIR** directory :!: the [[:arch:]]/ directory has not some env variable nor parameter )
  * CROSSFIRE_TREASURES //-treasures// ( relative/path/to/treasures //file// inside **LIBDIR** directory )
  * CROSSFIRE_UNIQUEDIR //-uniquedir// ( relative/path/to/unique-items //dir// inside **LOCALDIR** directory )
  * CROSSFIRE_TEMPLATEDIR //-templatedir// ( relative/path/to/template-maps //dir// inside **LOCALDIR** directory )
  * CROSSFIRE_**TMPDIR** //-tmpdir// ( **/absolute/**path/to/tmp //directory// )

From server/common/init.c :
<code C>

/** init_environ initializes values from the environmental variables.
 * it needs to be called very early, since command line options should
 * overwrite these if specified.
