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 the option "-T" is specified and 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, --eval=STRING
           Scan STRING as a string containing perl code.

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

       -x, --execute
           Executes the code and inspects its %INC, in addition to static scanning.  You may use --xargs to
           specify @ARGV when executing the code.

       --xargs=STRING
           If -x is given, splits the "STRING" using the function "shellwords" from Text::ParseWords and passes
           the result as @ARGV when executing the code.

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

       -R, --no-recurse
           Only show dependencies found in the files listed and do not recurse.

       -V, --verbose
           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, --cachedeps=CACHEFILE
           Use CACHEFILE to speed up the scanning process by caching dependencies.  Creates CACHEFILE if it does
           not exist yet.

       -T, --modtree
           Retrieves module information from CPAN if you have CPANPLUS installed.
