# Build just the the FrameCPP library, as a part of building GDS.
# Includes extra flags to use $HOME/lib and $HOME/include
# in the build, as I needed on building from $HOME on Debian Sarge
# (or modify for your own local build tools)
#
# Includes patches taken from External/patchall
#
# While this is just an outline of what you need to do, it is quite
# possible that you can just run this script from the GDS source directory,
# the External subdirectory, or the FrameCPP source directory under External.
# (No guarantees :-)
