Print a usage message from embedded pod documentation
PodUsage provides the function “pod2usage” to print usage messages for a Perl script based on its embedded pod documentation. PodUsage is a subclass of PodPlainText. Please see the POD documentation for this module embedded in the file “Usage.pm” for more details. The pod2usage function is probably the most generally useful function in this entire distribution since it is useful to just about any Perl5 script that is invoked from the command-line.
