TODO

- Implement support for Dia's new Database shape.

- Warn if there are typemaps for databases in the model that are not
  used to generate output.

- Add general support for synonyms (replace hack in
  Parse::Dia::SQL::Utils::get_base_type).

- Support index options on individual indices.

- Add test for missing FK (formerly fkNamesFromAttList)

- Add support for loading statements from external files.

- Warn on identical (or near-identical) statements in smallpackages.

- Warn attempts to create index on non-existent columns

- Add option tablespace to create statements.

- Add $VERSION to all modules.

- Make sure pre and post statement end up at the right place.

- Add options to parsediasql (identical to those of tedia2sql)

- For all classes:
  - verify create table,view,index,constraint syntax
  - verify drop table,view,index,constraint syntax

- Parse::Dia::SQL::Output::MySQL
    - sub _get_create_table_sql must handle AUTO_INCREMENT

- Download DDL's from http://tedia2sql.tigris.org/ and
  ensure Parse::Dia::SQL produces roughly the same code.

- Test with larger dia files.

- Optimize with Devel::DProf, and consider a faster XML parser.

- Be consistent in subroutine names (e.g. Output.pm)
  E.g. get_<dbobject>_<(create|drop)>_sql

- Apply stricter Perl::Critic (current level 'stern', consider
  'harsh').

- Update pod in all modules.
