# IMPORTANT:  This is extremely alpha!!!

# Note for gcc-3.1 users:  The produced build do not look as stable as it should
#                          be ... there are some weird glitches and crashes.

# notes:
# This will take a HELL of a long time to compile, be warned.
# According to openoffice.org, it takes approximately 12 hours on a
# P3/600 with 256mb ram.  And thats where building is its only task.
#
# It takes about 6 hours on my P4 1.8 with 512mb memory, and the
# build only needs about 2.1GB of disk space - Azarah.
#
# You will also need a bucketload of diskspace ... in the order of
# 4-5 gb free to store all the compiled files and installation
# directories.
#
# The information on how to build and what is required comes from:
# http://www.openoffice.org/dev_docs/source/build_linux.html
# http://tools.openoffice.org/ext_comp.html
#
# todo:
# Some kind of install process.  Works mostly, but the xml registry
# needs to be updated via a script or some program, not a tarball.
