    This is wrong as per POSIX
(<http://www.opengroup.org/onlinepubs/000095399/functions/unlink.html>):

[EPERM]
The file named by path is a directory, and either the calling process
does not have appropriate privileges, or the implementation prohibits
using unlink() on directories.

    ... and the current manpage ...

     [EPERM]            The named file is a directory.

    The manpage needs to be modified to note that, or the offender
needs to be fixed.

Thanks,
