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.
