commit b4f12ca39108269a5ca55e0925ae2046965d3083

Date:   Tue Jan 28 14:26:38 2014 +0000

    include/stap-probe.h: Add comment about SystemTap argument format
    
    Add a comment pointing to the SystemTap wiki page that documents the
    format of the arguments. Also add a pointer to the SystemTap and
    gdb sources which seem to be the best place to get the architecture
    specific details.
