Where to put common method?

Unity Engine

I have a number of utility functions that I would like to call from any script. Where can I put them so that the functions are visible to all the other scripts?

Thanks.

I have some utility functions that for convenience I placed all in one file (called Options.js, not a great name) and declared them static, so I could easily reference from other scripts and call them like Options.myutil();

Sweet! Thanks.
