DESCRIPTION = "Sanitized set of 2.6 kernel headers for the C library's use."
# This package is derived from the original linux-libc-headers at
#   http://ep09.pld-linux.org/~mmazur/linux-libc-headers/
# More specifically, llh-2.6.12.0 was patched up to 2.6.16-rc6 with 
# the official linux patches (where applicable) and then fixed up just
# enough to build glibc-2.4. BEWARE!
#
# license note from the linux-libc-headers package: 
#   Linux-libc-headers are derived from linux kernel headers. For license of a
#   particular header, check it's content, and if copyright notice isn't present,
#   standard linux kernel license applies. 
# since we assume GPL for linux i think we can also assume it here
