       scandeps - Scan file prerequisites

           % 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

       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 "" or
       "") 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.

       -e, --eval=STRING
           Scan STRING as a string containing perl code.

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

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

           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

       -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
