1598 * Convert the cscope output into a ctags style entry (as might be found |
| 7 | 1599 * in a ctags tags file). there's one catch though: cscope doesn't tell you |
| 1600 * the type of the tag you are looking for. for example, in Darren Hiebert's | |
| 1601 * ctags (the one that comes with vim), #define's use a line number to find the | |
| 1602 * tag in a file while function definitions use a regexp search pattern. | |

1604 * I'm going to always use the line number because cscope does something |
| 7 | 1605 * quirky (and probably other things i don't know about): |
| 1606 * | |
| 1607 * if you have "# define" in your source file, which is | |
| 1608 * perfectly legal, cscope thinks you have "#define". this | |
| 1609 * will result in a failed regexp search. :( | |
