/* vi:set ts=8 sts=4 sw=4:
 *
 * CSCOPE support for Vim added by Andy Kahn <kahn@zk3.dec.com>
 * Ported to Win32 by Sergey Khorev <khorev@softlab.ru>
 *
 * The basic idea/structure of cscope for Vim was borrowed from Nvi.
 * There might be a few lines of code that look similar to what Nvi
 * has.  If this is a problem and requires inclusion of the annoying
 * BSD license, then sue me; I'm not worth much anyway.
