* =================================================================== |
3 |
|
|
* This code was more or less cloned from the ircd-hybrid 5.3 source. |
4 |
|
|
* The original code was written by Otto Harkoonen and even though it |
5 |
|
|
* it not entirely in synch with section 2.2 of RFC1459 in that it |
6 |
|
|
* additionally defines carat as an uppercase version of tilde, it's |
7 |
|
|
* what is in the servers themselves so we're going with it this way. |
8 |
|
|
* |
9 |
|
|
* If for some reason someone who maintains the source for ircd decides |
10 |
|
|
* to change the code to be completely RFC compliant, the change here |
11 |
|
|
* would be absolutely miniscule. |
12 |
|
|
* |
13 |
|
|
* BTW, since carat characters are allowed in nicknames and tildes are |
14 |
|
|
* not, I stronly suggest that people convert to uppercase when doing |
15 |
|
|
* comparisons or creation of hash elements (which tcl laughably calls |
16 |
|
|
* arrays) to avoid making entries with impossible nicknames in them. |
