2dnl AC_FIND_MOTIF : find OSF/Motif or LessTif, and provide variables
3dnl     to easily use them in a Makefile.
4dnl
5dnl Adapted from a macro by Andreas Zeller.
6dnl
7dnl The variables provided are :
8dnl     MOTIF_LDFLAGS              (e.g. -L/usr/lesstif/lib -lXm)
9dnl     MOTIF_INCL           (e.g. -I/usr/lesstif/lib)
10dnl     motif_libraries         (e.g. /usr/lesstif/lib)
11dnl     motif_includes          (e.g. /usr/lesstif/include)
12dnl
13dnl The MOTIF_LDFLAGS and MOTIF_INCL variables should be fit to put on
14dnl your application's link line in your Makefile.
