POD - Perl POD File
This file type is a text file used to document source code written in Perl. This program language uses basic syntax that is easy to parse and read as source code format. POD is an acronym standing for 'Plain Old Documentation' and although it can be saved as a separate file, it may also be incorporated into the original Perl source code as well. These files oare most often used to document public domain Perl modules and for the Perl help manual, also known as the 'manpages'.
