2009-08-06 08:12 AEST by Arthur Barrett - enh: cvs diff/rdiff to support --brief:

cvs -q dif --brief -rFROM_TAG -rTO_TAG

This is already supported in GNU CVS 1.11.23:
http://ximbiot.com/cvs/manual/cvs-1.11.23/cvs_16.html#SEC138

'--brief'
Report only whether the files differ, not the details of the differences. 

It may be worth looking at what 'version' of diff CVS 1.11.23 is using to see if maybe CVSNT diff is 
getting a bit old, but I think from previous discussions the CVSNT diff includes some specific CVSNT 
things...

2009-08-06 08:16 AEST by Arthur Barrett - --brief appears to be identical to cvsnt diff -s, so just need to alias -s to '--brief'.

2009-08-06 08:33 AEST by Arthur Barrett - The 'cvs diff' command already supports --brief, but the output of 'rdiff -s' vs. 'diff --brief' are 
considerably different.

The output of -s is 'nicer' - certainly more usable...
