NAME
cpants_lint - commandline frontend to Module::CPANTS::Analyse SYNOPSIS
cpants_lint path/to/Foo-Dist-1.42.tgz Options: --help brief help message --man full documentation --verbose print more info during run --no_capture don't turn on capturing of STDERR and STDOUT --dump dump result using Data::Dumper --yaml dump result as YAML --to_file dump result to a file --dir directory to dump files to DESCRIPTION
"cpants_lint" checks the Kwalitee of CPAN distributions. More exact, it checks how a given tarball will be rated on "http://cpants.perl.org", without needing to upload it first. "cpants_lint" is also used by "cpants.perl.org" itself to check all dists on CPAN. For more information on Kwalitee, and the whole of CPANTS, see "http://cpants.perl.org" and / or "Module::CPANTS::Analyse". OPTIONS
If neither "--dump" nor "--yaml" are used, a short text describing the Kwalitee of the distribution and hints on how to raise Kwalitee will be displayed. The format of this text can change anytime, so don't use it for any automated processing! --help Print a brief help message. --man Print manpage. --verbose Print some informative messages during testing of dists. --no_capture Turn off capturing of STDOUT and STDERR. Mostly useful during debugging / development of new features. If "--no_capture" is used, the value of "cpants_error" might be wrong. --dump Dump the result using Data::Dumper --yaml Dump the result as YAML. --to_file Output the result into a file instead of STDOUT. The name of the file will be Foo-Dist.yaml (well, the extension depends on the dump format and can be ".yaml", ".dump" or ".txt") --dir Directory to dump files to. Defaults to the current working directory. AUTHOR
