# coin-config -- a utility for retrieving configuration information about
# the installed Coin library.
#
# Authors:
#   Lars J. Aas <larsa@coin3d.org>
#   Morten Eriksen <mortene@coin3d.org>
#
# Ideas for Improvements:
# - obsolete src/data/draggerDefaults/iv2h.sh by integration
# - make builds with subdir-based source files work properly
# - enable builds with source<->object file timestamp comparisons
#   (--make instead of --build?)
