## This makefile should be included using 
##     include $(top_srcdir)/Makefile.swig
## in Makefile.am's which require SWIG wrapping / compilation.
## For just installing .i files, this Makefile is not required.

## swig flags
## -w511 turns off keyword argument warning
## "-outdir $(builddir)" writes all generated output files to
##   the local builddir (which should always be '.')
##   In some older autotools, $(builddir) is not defined, so
##   just use '.' instead.
