I don't use Gemini, but I do know what CDPATH is, from using ksh and
bash.  The CDPATH variable contains a list of directories to scan for
a directory name given to the 'cd' command.  For example, if my CDPATH
is ":/usr:/usr/entropy:/usr/bob/pub/bin/bsd4.3/recreation" then
if I type "cd games" the shell will:

1) cd to ./games if it exists (some shells don't do this if you have a CDPATH)
2) otherwise, cd to /usr/games if it exists
3) otherwise, cd to /usr/entropy/games if it exists
4) otherwise, cd to /usr/bob/pub/bin/bsd4.3/recreation/games if it exists

CDPATH is very useful if you have long paths to very common storage
areas and don't like typing them all the time.
