Okay.

All of the operations which happen outside of a checked-out CVS tree
will have the same error when no CVSROOT is specified:

        cvs history
        cvs import
        cvs init
        cvs rdiff
        cvs rlog
        cvs rtag
        cvs version

When main.c::main() runs, it processes its arguments and next checks to
see if the environment looks okay (has a CVSROOT) before calling the
code to process the appropriate sub-command. Because there is no
CVS/Root or CVSROOT set already in your example, the code fails before
the sub-command is even called. Look in src/main.c to see how
CVSroot_parsed is set and what happens when it is not set.

So, if you have a CVSROOT environment variable pointing at something
reasonable, then a 'cvs import -h' will probably do what you expect.
