Why limon?

This script written in bash, which faster than Python. Yes, Python scripts are much easier to write and maintain than Bash scripts, but invoking Python interpreter introduces noticeable delay to output. I hate delays, so I wrote the part which I need, with pure Bash script.

The other reason is that I don't like the idea of patching fonts. The font patching mechanism does not work with the bitmap font (Apple Monaco without antialiasing) I use on non-retina screens. I'd rather stick with existing unicode symbols.

if you have any ideas send them and we going to make better program.
