From: Sibi Siddharthan <sibisiddharthan.github@xxxxxxxxx>
Implement the placeholder substitution to generate scripted
Porcelain commands, e.g. git-request-pull out of
git-request-pull.sh
Generate shell/perl/python scripts and template using CMake instead of
using sed like the build procedure in the Makefile does.
The text translations are only build if `msgfmt` is found in your path.
NOTE: The scripts and templates are generated during configuration.
