# User specified paths:
#    EZSDK_INSTALL_DIR 
#        location of EZSDK installation directory; settings from the DVSDK's
#        Rules.make will be used for the build.
#    TARGET_ROOT_DIR 
#        root directory of target filesystem on host machine
#    GSTREAMER_DIR
#        location of gstreamer installation on target filesystem.  This setting
#        should assume that "/" is the root file system of the target, not the
#        host.
#    CROSS_COMPILER
#        Cross compiler being used.  A default is chosen based on the platform
#        you are building for, but you can set it explicitly to one of these
#        values:
#            MVL_5_0:    MontaVista   v5.0
#            CS_2008Q1:  CodeSourcery v2008q1
#            CS_2009Q1:  CodeSourcery v2009q1
#    GST_TI_PLATFORM
#         In most cases this variable will be automatically set to be the same
#         as the PLATFORM variable in the Rules.make for the DVSDK.  Currently
#         the only time it must be set here is when building for dm6467 or
#         dm6467t.
#
# These paths must be specified or the build will fail.
