My idea is that someone might look in this dictionary to see what a file is and how it was created. Some files one might see in a distribution and wonder what is does (e.g. test.pl), might show up as a developer snapshot (e.g. MANIFEST.SKIP), or might be a particular sort of file in a perl lib directory (e.g. the .al files that AutoSplit creates).

I'm documenting special file names, file extensions, and such that a Perl user may run into. I learn about these things by looking at source or watching things run, but I don't think everyone should have to do that.
