/* userkfuncs.c: template file for a user set of
**               switchable kinematics functions.
** License GPL Version 2
**
** Example Usage (for customizing the genser-switchkins module):
** (works with rtpreempt only rtai --> Makefile needs work)
**
**        LDIR is LinuxCNC git root directory
**        UDIR is user directory (not in LinuxCNC git tree)
**  1) $ cp LDIR/src/emc/kinematics/userkfuncs.c  UDIR/my_userk.c
**  2) $ edit   UDIR/my_userk.c as required
**  3) $ source LDIR/scripts/rip-environment
**  4) For genser-switchkins module use make command line option:
**     $ cd LDIR/src
**     $ userkfuncs=UDIR/my_userk.c make && sudo make setuid
