(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 <patrick.georgi@coresystems.de> Acked-by: Stefan Reinauer <stepan@coresystems.de> Acked-by: Ronald G.
