   9   dbicdump [-o <loader_option>=<value> ] <schema_class> <connect_info>
  10
  11 =head1 DESCRIPTION
  12
  13 Dbicdump generates a L<DBIx::Class> schema using
  14 L<DBIx::Class::Schema::Loader/make_schema_at> and dumps it to disk.
  15
  16 You can pass any L<DBIx::Class::Loader::Base> constructor option using
  17 C<< -o <option>=<value> >>. For convenience, option names will have C<->
  18 replaced with C<_> and values that look like references or quote-like
  19 operators will be C<eval>-ed before being passed to the constructor.
  20
  21 The C<dump_directory> option defaults to the current directory if not
  22 specified.
