+fatunpack - Unpacker for App::FatPacker packets
+
+=head1 SYNOPSYS
+
+fatunpack [OPTION…] [PACKED_SCRIPT…]
+
+=head1 DESCRIPTION
+
+This tool unpacks scripts packed with App::FatPacker.
+
+Packed script's file names are specified as positional arguments. If no
+argument is given, a script from standard intput will be processed.
+
+The content of packed script stripped of all bundled modules is written to
+standard output.
+
+=head1 OPTIONS
+
+=over 8
+
+=item B<--libdir DIRECTORY>
+
+Directory to output unpacked modules to that where bundled into the input
+script. Default value is C<lib>.
+
+=item B<--filter REGULAR_EXPRESSION>
+
+Save only modules whose file name matches the B<REGULAR_EXPRESSION>. The file
+names are compared without B<--libdir> prefix. The expession is not anchored
+by default. Empty expression matches any file name. Default value is empty
+regular expression, i.e. to save all modules.
