=head1 NAME

PrepRel - Prepares a component for release.

=head1 SYNOPSIS

  preprel [options] <component> [<version>] [<internal_version>]

options:

  -h             help
  -m <mrp_name>  specify a new mrp file name
  -v             verbose output (-vv very verbose)

=head1 DESCRIPTION

Before a component can be released, it's environment database status must be set to I<pending release>. Also, a new version (and optionally internal version - note, if the C<reltools.ini> keyword C<require_internal_versions> has be set, an internal version is manatory) must be specifed. C<PrepRel> provides a means of editing this information in the environment database. To check that the values have been correctly updated, use C<EnvInfo>. Note, this will now take longer to run because the information in the F<mrp> files of the components pending release will need to be gathered. To remove the environment database entry for a component altogether, execute C<PrepRel> with no version.

Note, C<PrepRel> (and its counterpart C<PrepEnv>) do nothing more than update your the environment database. You can execute these commands as many times as you like before running C<MakeEnv> to actually release the environment.

=head1 KNOWN BUGS

None.
