Options:
-b boardnum     Specify board number of live FEP
-d device       Specify device or core image file [/dev/dm/ram0]
-o offset       Offset in device or file to map (use with -d /dev/kmem)

                Each bit in the mask represents a CSC channel
                0x1=CSC chan 0, 0x2=chan1, 0x4=chan2, 0x8=chan3, ...
-f              Run forever (like tail -f).  Else print buffer and stop.
-H timestamphz  Override timestamp HZ for use with the -R option.
-q              Quiet.  Do not print anything to stdout.  Used with -w.
-r file         Read (replay) events from a file
-R file         Read (replay) raw events from a file (no header info in file).

                        Use -H to use a different timestamp HZ with the -R optio
n.
-w file         Write (log) events to a file
-e evmask       Set event mask [0xC0000001]:
