Does anyone have any suggestions for a good cross platform input library?
I'd like to get:

```
* at least keyboard and mouse input
* on at least the big three operating systems
* Small/fast
* C or C++
* permissive licensing gpl2/mit/free/etc.

```

So far I've seen:

```
* OIS (used in Ogre) http://sourceforge.net/projects/wgois/
* SDL (used everywhere it seems, might be a clue) http://www.libsdl.org/index.php
* Allegro http://www.talula.demon.co.uk/allegro/readme.html

```

Has any one used any of these, or know of something else that might be good?

Thanks
