C<_generic> exists for when you for some reason are sure that your SQL is
generic enough to run on all databases. Good luck with that one.
+Note that unlike most steps in the process, C<preinstall> will not run SQL, as
+there may not even be an database at preinstall time. It will run perl scripts
+just like the other steps in the process, but nothing is passed to them.
+Until people have used this more it will remain freeform, but a recommended use
+of preinstall is to have it prompt for username and password, and then call the
+appropriate C<< CREATE DATABASE >> commands etc.

=head1 PERL SCRIPTS
-A perl script for this tool is very simple. It merely needs to contain a
-sub called C<run> that takes a L<DBIx::Class::Schema> as it's only argument.
+A perl script for this tool is very simple. It merely needs to contain an

will be stored.
