# This script will install, XLXD, YSFREFlector, and YSF2DMR
# for the purpose of having a tri mode transcoding server.

# and configure apache.
# Because of the simplicity around installing AMBED, it will
# not be installed via this script. I dont know where
# you will install it and building logic around that will take
# time. When Version 1 gets released, it will have that feature,
# along with many more.
# This script is just a proof of concept and will be itterated over time.
# Stay tuned...
