cvs-examine is an interactive autoloaded compiled Lisp function in `pcvs.el'.

(cvs-examine DIRECTORY FLAGS &optional NOSHOW)

Run a `cvs -n update' in the specified DIRECTORY.
That is, check what needs to be done, but don't change the disc.
Feed the output to a *cvs* buffer and run `cvs-mode' on it.
With a prefix argument, prompt for a directory and cvs FLAGS to use.
A prefix arg >8 (ex: C-u C-u),
prevents reuse of an existing *cvs* buffer.
Optional argument NOSHOW if non-nil means not to display the buffer.
