cron visualizer

[peterman at eecs.tufts.edu (Charles Peterman)]

Nothing on Freshmeat fits the bill, so here is what I would do:

Grab the source for cron, specifically the parsing logic.
Rewrite it in perl, or wrap it in perl.
Write a perl (php, tk, ascii art) script to display
the parsed contents of the file.

If you know perl, the total task should be about a days worth of work.
If you don't, call it a learning experience.   Making it netwokr aware
shouldn't be that bad.


Share and enjoy,
