Wrong S, L. The problem is with documentation being displayed on search.cpan.org, not PAUSE. All PAUSE does is figure out what versions of what modules are in a distribution. It assumes something is a module if it matches "/package\s+[\w:]+\s*;/" so if you want to "hide" a module from the indexer, the trick is to write the package declaration thus:

package #
blahblahblah;
[download]

but you very rarely have to do this. And in any case, PAUSE doesn't index pure documentation files - if you look in 02packages, nary a mention will you find of Date::Manip::TZ::$module.

Unfortunately, the source for search.cpan.org isn't available. It's maintained by GBARR, so you might like to submit a bug report to him.
