Like git, but for managing the workflow around an intentional application.

Some ideas for the subcommands:

epi edit commands       -- edit model/commands.xsd
epi edit events         -- edit model/events.xsd
epi edit MyAggregate    -- edit lib/MyAggregate.pm
epi edit -t MyAggregate -- edit t/myaggregate.t

epi test                -- run all tests
epi test MyAggregate    -- run t/myaggregate.t

epi newtest MyAggregate -- add a test
epi newtest MyAggregate -g Event1,Event2 -w Command3 -t Event4,Event4
                        -- add a test, events and commands pre-filled

epi edit                -- edit file/line, DWIM based on recent events

epi make                -- rebuild Makefile, run make

The test cases are meant to be central to it all, so

• Saying "I want to implement this test" will set things up properly and take you to the relevant file and line in vim.

• Mentioning a new type of command, event, or attribute to a command or event will automatically trickle back into the model.

• It just keeps making git commits with excellent commit messages all the time through this.
