Alpha release 8/25/97

NOTES
Makefile is for AT&T nmake, available as part of "astkit" at
	http://akpublic.research.att.com:9000/sw/tools/reuse/
	The entire build is controlled from the Makefile.

makefile is for old make (works with GNU) and employs recursive makes.
	Run configure in the parent directory to generate the Config.mk
	file that contains all platform dependent information for the makefiles.

The makefiles build the path planner library.  A companion directory
Tclpath provides an interactive front end for demos. 

The library is still being developed.  Our plan is to clean up the
internal interfaces (where data structures are needlessly copied
and converted so we could glue in some older code).  We also changed
the spline fitter router so that the output spline is not forced to
hit all the points of the input path.  We plan to extend the library
interface to let the caller to say which path points must be hit.
