Synopsis:
   cd [<path>]

Description:
   This is used to change the current working directory.  If a path is
   specified, the client will try to change to that directory; else, it
   displays the current directory.  This is useful for other commands
   that deal with files but don't necessarily use absolute pathnames,
   such as EXEC, log files, or DCC file transfers.

See Also:
   which(4); which(6)

Other Notes:
   CD is smart enough to expand tildes (~) to the user's home directory.
