cvs2p4-ft: Readme type modifications.
Latest modifications and READMEs.
MANIFEST still doesn't know about the *.c OpenRCS files, but at at
least the files as they are now, have been proven to convert a large
CVS repository to a 350,000+ Perforce repository, ignoring the more
egregious corruptions that exist within that repository.
The idea here is that people would rather get whatever they can get
from a corrupted CVS repository without working through large-scale
CVS repositories manually to make the data acceptable to the stock
converter.
