NAME
     pmload - show what files a given module loads at compile
     time

DESCRIPTION
     Given an argument of a module name, show all the files that
     are loaded directly or indirectly when the module is used at
     compile-time.

EXAMPLES
         $ pmload IO::Handle
         /usr/local/devperl/lib/5.00554/Exporter.pm

         /usr/lib/perl5/site_perl/Tk/Widget.pm

NOTE
     If the programmers used a delayed "require", those files
     won't show up.  Furthermore, this doesn't show all possible
     files that get opened, just those that those up in %INC.
     Most systems have a way to trace system calls.  You can use
     this to find the real answer.  First, get a baseline with no
     modules loaded.

         $ strace perl -e 1 2>&1 | perl -nle '/^open\("(.*?)".* = [^-]/ && print $1'
         /etc/ld.so.cache
         /lib/libnsl.so.1
         /lib/libdb.so.2
         /lib/libdl.so.2
         /lib/libm.so.6
         /lib/libc.so.6
         /lib/libcrypt.so.1
         /dev/null

         $ strace perl -e 1 2>&1 | grep -c '^open.*= [^-]'
         8

     Now add module loads and see what you get:

         $ strace perl -MIO::Socket -e 1 2>&1 | grep -c '^open.*= [^-]'
         24

         $ strace perl -MTk -e 1 2>&1 | grep -c '^open.*= [^-]'
         35
