NAME

       Module::Versions::Report -- report versions of all modules in memory

SYNOPSIS

         use Module::Versions::Report;

         ...and any code you want...

       This will run all your code normally, but then as the Perl interpreter is about to exit,
       it will print something like:

         Perl v5.6.1 under MSWin32.
          Modules in memory:
           attributes;
           AutoLoader v5.58;
           Carp;
           Config;
           DynaLoader v1.04;
           Exporter v5.562;
           Module::Versions::Report v1.01;
           HTML::Entities v1.22;
           HTML::HeadParser v2.15;
           HTML::Parser v3.25;
           [... and whatever other modules were loaded that session...]

       Consider its use from the command line:

         % perl -MModule::Versions::Report -MLWP -e 1

         Perl v5.6.1 under MSWin32.
          Modules in memory:
           attributes;
           AutoLoader v5.58;
           [...]

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 relevent 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 relevent
       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).

USING

   Importing
       If this package is imported then END block is set, and report printed to stdout on a
       program exit, so use "use Module::Versions::Report;" if you need a report on exit or "use
       Module::Versions::Report ();" otherwise and call report or print_report functions
       yourself.

   report and print_report functions
       The first one returns preformatted report as a string, the latter outputs a report to
       stdout.
