Changes in version 1.5-9 (2013-03-22)                  

    o   Support for user-supplied basis function has been withdrawn until further notice.

    o   Changed akima from Import to Suggest.  The interp() function from akima is used 
	conditionally in preplot.locfit().  Anyone who needs it will have to install
	akima, whose license is more restrictive than locfit's.  If it's needed but 
	not available, an error message is given with a note regarding the license.

                 Changes in version 1.5-8 (2012-04-25)                  

    o   Added a subset method for the "lp" class to resolve the problem that in a locfit()
	call, if "subset" is given then any optional argument to lp() are ignored.

                 Changes in version 1.5-7 (2012-03-25)                  

    o   Patches by Brian Ripley (added NAMESPACE, changed Call_S(), etc.)

                 Changes in version 1.5-6 (2010-01-21)                  

    o   Added check for 0-row data so locfit() won't segfault.

                 Changes in version 1.5-5 (2010-01-07)                  

    o   Patches provided by Brian Ripley to clean up some function arguments and
	documentations.
