From 75eef34a23ac60b9218a6fa3da80f579b6830303 Mon Sep 17 00:00:00 2001 From: Tim Potter Date: Wed, 28 Apr 2004 10:10:52 +0000 Subject: r383: Scripting extensions using swig. This commit includes only a (LGPL) python interface to tdb and a rudimentary build system. Configure with --with-python and make swig to build and append $(builddir)/scripting/swig/python to PYTHONPATH.
