41 | /* TODO notes | |
42 | * | |
43 | * - Implement most of proto-p10 irc_* commands for calling from scripts | |
44 | * - Implement functions to look up whois, channel, account, and reg-channel info for scripts | |
45 | * - Implement x3.conf settings for python variables like include path, etc. | |
46 | * - modpython.py calls for everything you can reg_ a handler for in x3 | |
47 | * - Some kind of system for getting needed binds bound automagicaly to make it easier | |
48 | * to run peoples' scripts and mod-python in general. | |
49 | * - An interface to reading/writing data to x3.db. Maybe generic, or attached to account or channel reg records? | |
