in reply to creating a perl entry-point

roboticus has good points. I would add the following only as an additional consideration:

use strict; use warnings; main(); # always have an exit from a script, it will save you grief! exit; sub main { ... # do some really cool stuff here # always have a known return value, just falling off the end WILL +bite # bite you someday. return; } __END__

The use of exit and __END__ can prevent unexpected additions to your script for one reason or another. It is also handy to have all your POD (you do document your code, right?) after the __END__ statement.

It helps to remember that the primary goal is to drain the swamp even when you are hip-deep in alligators.
