Prettydot - Human readable dot graph language for CFG

• Background
• Usage
• Compilation

Background

[Dot][] is a graph description language in extensions .dot or .gv, and can be read by programs such as Graphviz ([try it online][]). However, it's syntax is too complicated for the goal of generating a simple control-flow graph, and is not very well human readable. Therefore, I defined a new language, prettydot, for this purpose.
