| 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. | |

| 9 * See README.txt for an overview of the Vim source code. | |
