Update to 1.15, old distfile vanished.
Changes:
* Add COPYRIGHT AND LICENSE to Resource.pm.
* A space between the 2>/dev/null and the command is nice.
* I suck.  Vivek Khera reported NINE MONTHS ago that
  I was missing sub isrss().  My memory was jogged by
  a message from Jeff Boes ONE MONTH ago.  My apologies.
