Re: [PATCH v2 0/4] Build improvements for clar

[Phillip Wood <phillip.wood123@gmail.com>]

Hi Patrick

I've not actually tested them but having read through them these patches 
look good to me. While it may be a bit ugly to have an awk script 
lurking inside a shell script it does mean if we ever change the 
implementation of the shell script to process the files in a different 
way we wont have to worry about updating the build system(s).

Best Wishes

Phillip
