typesetting an algorithm

[Raphael Clifford]

I am writing a paper in article (AMS) and need to typeset some 
algorithms.  I see that there is an algorithm environmnent defined. I am 
sorry if I have missed them but are there any docs for using this 
environment in lyx?  It is not clear to me what the correct way to do 
the indentation etc is.

Cheers,
Raphael
