Subject: [gentoo-dev] [PATCH] python-r1: introduce PYTHON executable getter.

[Download RAW message or body]
A semi-replacement for _python-distutils-ng_very_long_name...
Unlike the forementioned function, it returns just the binary name
and not the complete path. Thus, the executable rewrite in p-d-ng has
been changed to use #!/usr/bin/env.
