Description:
module for including constants from POD
This module allows you to specify those constants that should be documented in your POD, and pull them out a run time in a fairly arbitrary fashion. . Pod::Constants uses Pod::Parser to do the parsing of the source file. It has to open the source file it is called from, and does so directly either by lookup in %INC or by assuming it is $0 if the caller is "main" (or it can't find %INC{caller()})
