Subject: [Boost-commit] svn:boost r53655 - in trunk: boost/graph libs/graph/doc libs/graph/test
From: jewillco_at_[hidden]
Date: 2009-06-05 14:21:43
Author: jewillco
Date: 2009-06-05 14:21:42 EDT (Fri, 05 Jun 2009)
New Revision: 53655
URL: http://svn.boost.org/trac/boost/changeset/53655
Log:
Reverted old version of CSR graph for compatibility, with a #define to switch between the modes; cleaned up interface of new CSR graph; fixed tests and docs accordingly
