[Met_help] Information about accumulation precipitation

[John Halley Gotway]

Francesco,

Thank you very much for sending the page numbers.  We'll update the User's Guide to indicate that the output of PCP-Combine may be used with any of the MET statistics tools (Point-Stat, Grid-Stat,
MODE, Wavelet-Stat).  When maintaining a document that large, errors are bound to slip through.  It's nice to know that there are MET users reading it closely!

Thanks,
John
