Description:

I often get email from someone reporting a bug in a module I've written.
I email back, asking what version of the module it is, what version of
Perl on what OS, and sometimes what version of some relevant third library
(like XML::Parser). They reply, saying "Perl 5". I say "I need the exact
version, as reported by `perl -v`". They tell me. And I say "I, uh,
also asked about the version of my module and XML::Parser [or whatever]".
They say "Oh yeah. It's 2.27". "Is that my module or XML::Parser?"
"XML::Parser." "OK, and what about my module's version?" "Ohyeah.
That's 3.11." By this time, days have passed, and what should have been
a simple operation - reporting the version of Perl and relevant modules,
has been needlessly complicated.

This module is for simplifying that task. If you add "use
Module::Versions::Report;" to a program (especially handy if your program
is one that demonstrates a bug in some module), then when the program
has finished running, you well get a report detailing the all modules
in memory, and noting the version of each (for modules that defined a
$VERSION, at least).
