Update of /cvsroot/pure-data/externals/deprecated
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv17141/deprecated
Added Files:
Makefile linuxevent.c linuxhid.h linuxmouse.c pan_gogins~.c
range.c
Log Message:
cleaned up buildsrc and unfiltered sections and turned them into libdirs; made 'pan' libdir and cleaned up source dir for easy makefile install rules; created 'deprecated' libdir and moved cruft there
