From 3b3fd33190d89c09e62126eea0e45aa84fe5442e Mon Sep 17 00:00:00 2001 From: Paul Eggleton Date: Tue, 22 Dec 2015 17:03:02 +1300 Subject: recipetool: create: support extracting name and version from build scripts Some build systems (notably autotools) support declaring the name and version of the program being built; since we need those for the recipe we can attempt to extract them. It's a little fuzzy as they are often omitted or may not be appropriately formatted for our purposes, but it does work on a reasonable number of software packages to be useful.
