-=head1 NAME
-
-CPANPLUS::Module::Checksums
-
-=head1 SYNOPSIS
-
- $file = $modobj->checksums;
- $bool = $mobobj->_validate_checksum;
-
-=head1 DESCRIPTION
-
-This is a class that provides functions for checking the checksum
-of a distribution. Should not be loaded directly, but used via the
-interface provided via C<CPANPLUS::Module>.
-
-=head1 METHODS
-
-=head2 $mod->checksums
-
-Fetches the checksums file for this module object.
-For the options it can take, see C<CPANPLUS::Module::fetch()>.
-
-Returns the location of the checksums file on success and false
-on error.
-
-The location of the checksums file is also stored as
-
- $mod->status->checksums
-
