* I designed this trie to parse ircd commands. Hence it currently |
| 59 |
|
* casefolds. This is trivial to fix by increasing MAXPTRLEN. |
| 60 |
|
* This trie also "folds" '{' etc. down. This means, the input to this |
| 64 |
|
* MAXPTRLEN 128. |
| 65 |
|
* |
| 66 |
|
* This is also not a patricia trie. On short ircd tokens, this is |
| 67 |
< |
* not likely going to matter. |
