Well, it's just a script you put in your bot.
Commands:

!addquote (quote): add a quote
!quote (number): shows the quote number
!rquote: random quote
!dquote (number): deletes a quote (only if you're opped on that channel)
!quotes: tells you the number of quotes you have.

Yeah. . .it's pretty self-explanatory.
