From 7e8c9aa271f13f67e4fc4968d2bf6fb8e5b229d7 Mon Sep 17 00:00:00 2001 From: Patrick Georgi Date: Thu, 8 Apr 2010 11:37:43 +0000 Subject: Replace sconfig with a C implementation. (smaller, faster, standard parser generator, no more python) Provide precompiled parser, so bison and flex are optional dependencies. Adapt Makefile and abuild (which uses some sconfig file as a magic path) to match. Drop python as dependency from README, and add bison and flex as optional dependencies Signed-off-by: Patrick Georgi Acked-by: Stefan Reinauer Acked-by: Ronald G.
