 I recommend you using some basic versioning for your code, even though you submit
 only the sources on _aisa_. There are specific reasons why I suggest it:
 
-- once you submit the sources for evaluation, there is no way of getting previous
-  submissions
-
-  i.e. if you introduce new bugs between submissions, you cannot compare two of
-  them to pinpoint the bug, this can be easily resolved by _git tags_

 - if you build a _commit, tag and submit_ habit, you might be able to address

 Since frag creates a lot of support files (majority of them are dotfiles, i.e.
 hidden files), I recommend you to use following

-It allows me to comment on your source code with an option for you to reply, so
