=head1 NAME

install-module.pl - Installs or upgrades modules from CPAN.
This script does not run on Windows.

=head1 SYNOPSIS

  ./install-module.pl Module::Name [--global]
  ./install-module.pl --all [--global]
  ./install-module.pl --all-upgrade [--global]
  ./install-module.pl --show-config

  Do "./install-module.pl --help" for more information.

=head1 OPTIONS

=over

=item B<Module::Name>

The name of a module that you want to install from CPAN. This is the
same thing that you'd give to the C<install> command in the CPAN shell.

You can specify multiple module names separated by a space to install
multiple modules.

=item B<--global>

This makes install-module install modules globally for all applications,
instead of just for Bugzilla.

On most systems, you have to be root for C<--global> to work.

=item B<--all>

This will make install-module do its best to install every required
and optional module that is not installed that Bugzilla can use.

Some modules may fail to install. You can run checksetup.pl to see
which installed properly.

=item B<--upgrade-all>

This is like C<--all>, except it forcibly installs the very latest
version of every Bugzilla prerequisite, whether or not you already
have them installed.

=item B<--show-config>

Prints out the CPAN configuration in raw Perl format. Useful for debugging.

=item B<--help>

Shows this help.
