Subject: cpt: print docstrings using awk instead of sed
Using awk, we can achieve the following things:
- Ignore the rest of the file (2 times faster than sed)
- If the line doesn't match the docstring pattern, we can just print a
newline instead.
I am not exactly really familiar with awk scripting so there might be a
better way of doing this. In that case please send a patch and I will
apply it.
