+Note that there can be an C<_any> in the place of any of the versions (like

=head1 PERL SCRIPTS
A perl script for this tool is very simple. It merely needs to contain an
-anonymous sub that takes a L<DBIx::Class::Schema> as it's only argument.
+anonymous sub that takes a L<DBIx::Class::Schema> and the version set as it's
+arguments.
+
A very basic perl script might look like:
#!perl
sub {
my $schema = shift;
+ # [1] for deploy, [1,2] for upgrade or downgrade, probably used with _any
+ my $versions = shift;
+
$schema->resultset('Users')->create({
name => 'root',
password => 'root',
probably the best plan of action as you will not be putting as many generated
files in your version control. Goes well with with C<databases> of C<[]>.
+=attr force_overwrite
+
+When this attribute is true generated files will be overwritten when the
+methods which create such files are run again. The default is false, in which
+case the program will die with a message saying which file needs to be deleted.
