Re: request for enhancement: annotate

[Aaron S. Hawley]

i can't find the place where i had read that `cvs annotate` is quite
difficult and slow (i believe it required checking each version out
separately then going through from start to finish to determnie the
history of a line in the file), but of course could be implemented in RCS
since, CVS uses the RCS version file format (uses reverse deltas).
revision annotation is much easier to do in SCCS where deltas are not
reverse.

here's some other notes.

blame.py - Annotate in Python
http://cvs.sourceforge.net/viewcvs.py/viewcvs/viewcvs/lib/blame.py

which uses vclib.ccvs.rcsparse:
http://cvs.sourceforge.net/viewcvs.py/viewcvs/viewcvs/lib/vclib/ccvs/rcsparse/

viewcvs also has tparse a C++ RCS parser with Python bindings:
