|
|
2 *
|
|
|
3 * CSCOPE support for Vim added by Andy Kahn <kahn@zk3.dec.com>
|
|
148
|
4 * Ported to Win32 by Sergey Khorev <sergey.khorev@gmail.com>
|
|
7
|
5 *
|
|
|
6 * The basic idea/structure of cscope for Vim was borrowed from Nvi. There
|
|
|
7 * might be a few lines of code that look similar to what Nvi has.
|
|
|
8 *
|
|
|
9 * See README.txt for an overview of the Vim source code.
