# Slackware build script for mlt.

# Written by stormtracknole - stormtracknole@gmail.com
# Modified by Erik Hanson (erik@slackbuilds.org) with
# help from Jonathan Larsen (agentc0re@learnix.net)
# Maintatiner: Edward W. Koenig <kingbeowulf@gmail.com>
#
# Feb 16, 2010 - Modified the script and defined the $PYTHON variable
#	outside of the if statement because it was causing issues with
#	the other if statement that also relies on it's answer.
#	- Fixed the second PYTHON if statement that finds the site package
#	directory.  Added parentheses around the part that cd's into the
#	python swig src to copy the files to the site packages so that it
#	would interfere with the CWD before it
