=head1 NAME
convert-db - A tool to convert backend database of Movable Type
=head1 SYNOPSIS
convert-db --new=mt-config.cgi.new [--old=mt-config.cgi.current]
=head1 DESCRIPTION
I<convert-db> is a tool to convert database of Movable Type to
others. It is useful when it is necessary to switch like from
MySQL to PostgreSQL.
The following options are available:
--new mt-config.cgi file of destination
--old mt-config.cgi file of source (optional)
It is also useful to replicate Movable Type database.
