       If the target program's code conditionally loads mor perl modules during  execution,  you  must  run  the
       program for real to have those modules detected.

       Uses standard Perl modules.

       Find out roughly the modules the program uses. This is based on the idea that Perl evaluates the "use"
       commands at compile time and stores the loaded module information in the %INC variable. By examining the
       loaded modules and comparing them against the standard Perl modules, the external module dependencies can
       be roughly dependencies.

       The dependency information can be used to determine what external modules have to be installed before the
       program can be used.

       The target FILE has to be instrumented (a comouting term to inject code) with the dependency checking
       code. The resulting script is then stored in a temporary file which the user runs.

       This program does not run the instrumented files because it cannot know what possible options need to be
       passed for programs to trigger nullbehavior. That is, something that doesn't actually involve executing
       the script for real. Such options might include --version, --dry-run, or options like
       --generate-syntax-error-now, or invalid arguments to make the program stop with an error. The user is
       more likely to know the best way of running the instrumented files.

       An example of output: the external module dependency here is 'Regexp::Common' and the rest of them can be
       ignored.

           Regexp::Common                 Regexp/Common.pm
           Regexp::Common::CC             Regexp/Common/CC.pm
           ...

       None.

       Instrument a file, run it to see the results and delete instrumentated script:

           perl-depends file.pl
           perl file.pl.tmp <followed by whatever args the program needs>
           rm *.tmp

       This program's exit status is not defined.

       The  instrumented  program's  exit  status  is  1  if external modules are displayed and 0 if no external
       modules are found.

       None.
