# This Makefile fragment is included by packages that use Motif.
#
# To use this Makefile fragment, simply:
#
# (1) Optionally set USE_MOTIF12 to use a Motif-1.2-compatible installation.
#     Otherwise, assume we want a Motif-2.0-compatible installation.
# (2) Optionally set MOTIFBASE or MOTIF12BASE to choose the Motif-2.0 or
#     Motif-1.2-compatible installation at the named location,
# (3) Or optionally set MOTIF_TYPE or MOTIF12_TYPE to choose a specific
#     Motif-2.0 or Motif-1.2-compatible package to be used,
# (4) And include this Makefile fragment in the package Makefile.
