# Description:

#   This macro locates the SoWin development system.  If it is found,

#   the set of variables listed below are set up as described and made
 
8
#   available to the configure script.

10
#   The $sim_ac_sowin_desired variable can be set to false externally to
 
11
#   make SoWin default to be excluded.

# Autoconf Variables:

# < $sim_ac_sowin_ldflags     (extra flags the linker needs)
 
18
# < $sim_ac_sowin_libs        (link library flags the linker needs)
 
19
# < $sim_ac_sowin_datadir     (location of SoWin data files)
