My understanding is that cprnc.ncl and its cprnc.pl wrapper exist only because the standard fortran-based cprnc wasn't able to compare files without a time dimension. As of cprnc_130529, this is fixed. So I propose removing these CLM-specific cprnc scripts, and switching testing to use the standard cprnc instead.

Advantages:

(1) no longer need to maintain these scripts

(2) I recently found a problem with the cprnc.ncl script - it doesn't flag files as different if they differ in where there are missing values (see bug 1714). The fortran-based cprnc handles this correctly

(3) The fortran-based cprnc gives you more information about differences than you can get from cprnc.ncl.

(4) Post-processing scripts that look at cprnc output (e.g., summarize_cprnc_diffs) don't work on cprnc.ncl output; so if we switch to using the fortran-based program, these post-processing scripts can be used.

We've done this, so closing.
