Tue May 5 06:22:11 2009 UTC (9 years, 11 months ago) by jfenwick
Original Path: trunk/bin/escript
File size: 13442 byte(s)
bin/escript is now under version control.
The wrapper template is no longer used.
Extraneous output doc removed from scons during build.

note: finleypython is no longer built (it was deprecated anyway).
