    Have it create a name based on the current date and time and allow the

    hammer snapshot <softlink-dir-in-filesystem>
    hammer snapshot <filesystem> <softlink-dir>

    So:

        hammer snapshot /usr/obj "/mysnapshots/obj-%s"

        -->  /mysnapshots/obj-20080625

        hammer snapshot /usr/obj "/mysnapshots/obj-%s-%s"

        -->  /mysnapshots/obj-20080625-1013

        hammer snapshot /usr/obj "/mysnapshots"

        --> /mysnapshots/snap-20080625-1013

    Or something like that.

Matt, I went with strftime for ultimate flexibility on how
the timestamp is formatted, so that the following works fine:

  hammer snapshot "/mysnapshots/snap-%Y-%m-%dT%H:%M:%S"
  hammer snapshot /obj "/mysnapshots/obj-%Y-%m-%dT%H:%M:%S"
