pr-command

pr-command is a compiled Lisp function in `printing.el'.

(pr-command COMMAND)

Return absolute file name specification for COMMAND.

If COMMAND is an empty string, return it.

If COMMAND is already an absolute file name specification, return it.
Else it uses `pr-path-alist' to find COMMAND, if find it then return it;
otherwise, gives an error.

When using `pr-path-alist' to find COMMAND, the entries `cygwin', `windows' and
`unix' are used (see `pr-path-alist' for documentation).

If Emacs is running on Windows 95/98/NT/2000, tries to find COMMAND,
COMMAND.exe, COMMAND.bat and COMMAND.com in this order.
