Subject: Initial Python 2.6 portability in SCons code itself, using subprocess
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=547a4cf69af42a299ae3c59a020a0e9470b898f3;p=scons.git

Initial Python 2.6 portability in SCons code itself, using subprocess
in place of popen2, and calling hashlib.md5() instead of the md5 module.
