Keywords: smail patch enhancement

Here is a small patch to smail 2.5 (comp.sources.unix, volume 11).
It adds the ability to create aliases which will pipe the mail
message into a program.

For example, you can receive news mailed to you by creating the
following alias:

	rnews:"|/usr/bin/rnews"

Apply this using patch:
