=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.
