# This file is responsible for extracting the x11 native struct offsets to

# the xawt Java library. The tool needs to be run on the os/arch that

# will host the final jvm, thus the tool cannot be used when cross compiling.

#

# Two versions of the generated offset file, sizes-32.txt and sizes-64.txt are

# committed into the source code repository. These are the ones used in

# GensrcX11Wrappers.gmk to generate the Java code during the build.
