This class is a very simple extension of Pod::Parser that extracts POD
snippets from Perl code, and pretty-prints it so as to make it usable from
other Perl code. As demonstrated above, Pod::Snippets is immediately useful
to test-driven-development nutcases who want to put every single line of
Perl code under test, including code that is in the POD (typically a
SYNOPSIS section). There are other uses, such as storing a piece of
information that is both human- and machine-readable (e.g. an XML schema)
simultaneously as documentation and code.
