The directory here exists for the submodule called E.

The reason for this strange name is that I used to do this a lot in ruby:

alias e puts

So in other words, I would be using ā€œeā€ rather than puts, in order to do output onto the commandline.

I also used to have this in another project called AliasE, but eventually I decided that I should put this right into the Colours project.
