Create a patch file that can convert a directory containing one release into a different release.

The standard meanings of the common client options -D, -f, -l, -r, and -R apply. Here are additional options:

-c

Use context diff format (the default).

-s

Output a summary of changed files instead of a patch file.

-t

Show the differences between the two most recent revisions.

-u

Use unidiff format.

-V rcsver

Obsolete. Used to specify version of RCS to emulate for keyword expansion. (Keyword expansion emulates RCS Version 5.)
