## Why
The main reason for starting this project it's because there are no fully free

Also, the existing tools are too complex and require too much knowledge to

## Todo
* Improve *help* option for commands.
* Allow to specify a custom workspace subdirectory inside project directory.
* Create a lock during push to avoid collisions.
* Update routines shasum when push.
* Use a custom *Dockerfile* for local database container.
* Console logging via events.
* Lock version table row when pushing.
