# This file is responsible for extracting the x11 native struct offsets to
# the xawt Java library. This is done by compiling and running a native
# binary, which dumps output to a text file. The offsets differ on 32 and 64
# bit systems, so care must be taken here.

# Note: Some of the more complex logic here is most likely not needed anymore.
