Is there an extended function library for SQLite?

Is there an e开发者_C百科xtended function library for sqlite?

I am trying out sqlite and realized that a lot of the functions I could expect to take for granted in other sql databases don't exist in it, although it appears they can be added to it.

Are there some ready made libraries like that for it?
