What I'm Currently Working on

• Add tests and examples directories.
• Improved minimise() algorithm.
• Support memory allocator parameter in templates.
• Use strong exception guarantee in rules class and anywhere else that it is reasonable to have it.
• Investigate auto minimisation of state machine.
• Recode char_state_machine to support re2c style generators.
• Write re2c style generator.

Outstanding Features

• Redo code generator (in the style of re2c with ^, $ and multi-state support).
• Investigate Ville Laurikari's tagged DFAs in more depth.
