NAME

       scandeps - Scan file prerequisites

SYNOPSIS

           % scandeps *.pm          # Print PREREQ_PM section for *.pm
           % scandeps -e 'STRING'      # Scan an one-liner
           % scandeps -B *.pm       # Include core modules
           % scandeps -V *.pm       # Show autoload/shared/data files
           % scandeps -R *.pm       # Don't recurse
           % scandeps -C CACHEFILE  # use CACHEFILE to cache dependencies

DESCRIPTION

       scandeps is a simple-minded utility that prints out the "PREREQ_PM" section needed by
       modules.

       If you have CPANPLUS installed, modules that are part of an earlier module's distribution
       with be denoted with "S"; modules without a distribution name on CPAN are marked with "?".

       Also, if the "-B" option is specified, module belongs to a perl distribution on CPAN (and
       thus uninstallable by "CPAN.pm" or "CPANPLUS.pm") are marked with "C".

       Finally, modules that has loadable shared object files (usually needing a compiler to
       install) are marked with "X"; with the "-V" flag, those files (and all other files found)
       will be listed before the main output. Additionally, all module files that the scanned
       code depends on but were not found (and thus not scanned recursively) are listed. These
       may include genuinely missing modules or false positives. That means, modules your code
       does not depend on (on this particular platform) but that were picked up by the heuristic
       anyway.

OPTIONS

       -e STRING
           Scan STRING as a string containing perl code.

       -c  Compiles the code and inspects its %INC, in addition to static scanning.

       -x  Executes the code and inspects its %INC, in addition to static scanning.

       -B  Include core modules in the output and the recursive search list.

       -R  Only show dependencies found in the files listed and do not recurse.

       -V  Verbose mode: Output all files found during the process; show dependencies between
           modules and availability.

           Additionally, warns of any missing dependencies. If you find missing dependencies that
           aren't really dependencies, you have probably found false positives.

       -C CACHEFILE
           Use CACHEFILE to speed up the scanning process by caching dependencies.  Creates
           CACHEFILE if it does not exist yet.
