The intent of File::ShareDir is to provide a companion to Class::Inspector and
File::HomeDir, modules that take a process that is well-known by advanced Perl
developers but gets a little tricky, and make it more available to the larger
Perl community.

Quite often you want or need your Perl module (CPAN or otherwise) to have
access to a large amount of read-only data that is stored on the file-system at
run-time.

On a linux-like system, this would be in a place such as /usr/share, however
Perl runs on a wide variety of different systems, and so the use of any one
location is unreliable.

Perl provides a little-known method for doing this, but almost nobody is aware
that it exists. As a result, module authors often go through some very strange
ways to make the data available to their code.

The most common of these is to dump the data out to an enormous Perl data
structure and save it into the module itself. The result are enormous
multi-megabyte .pm files that chew up a lot of memory needlessly.
