# INSTALLATION GUIDE FOR TRANSCODER UTILITIES
##############################################################################
# NOTE:
# These are the steps that work to install the various transcoder utilities
# and system tools that power the WordPress.com video subsystem.
#
# Currently this is mainly deployed on a standard Debian Etch installation
# on AMD64 processors (2.6.18-6-amd64) in our environment. 
#
# This should be used as a guide, rather than a step by step install routine.
# You might not need all of these utilities, or you might need more of them, 
# or, more likely, there are newer releases of these available and it will 
# probably make sense to use the latest releases. You might need different
# versions of these tools if you are on a different platform. 
#
# Some of these steps are Debian specific, some are not. Please use the tools
# available on your platform where needed.
