Benefit to Fedora

How To Test

There is no special hardware required to test Clean. You should install the package "clean".

There is a file with general tests available at:

You should save this file as general.icl and call "clm -nt general -o general".

This should generate the application "general", which, upon execution, should print the word "True".

This feature is not dependent on anything except upstream.

Contingency Plan
