# install_ace: distill the minimal stuff out of the ACE+TAO distribution
# alias cpio 'xargs -i echo {}'; # just for testing the script
#
# according to David Levine <levine@cs.wustl.edu> on 1999/01/09:
#
#     An even better way would be to only build what you need.
#     These directories are probably a good start:
#
#     ace
#     apps/gperf/src
#     TAO/tao
#     TAO/TAO_IDL
#     TAO/orbsvcs
#
#     netsvcs ? - not built in here, probably useful
