Makefile

## Generic Makefile to allow the octave-forge packages to be build and 
## installed using "configure; make all; make install". This Makefile
## includes the capability to install to a temporary location, and install
## an on_uninstall.m file that prevents the user removing this package
## with Octave's package manager. This is useful for for the distribution's
## various package managers and is forced by defining DESTDIR and DISTPKG.
