(clug-talk) vim auto indent?

[Jason Louie]

   Hello all, first I would like to thank Rob on his presentation on 
Emacs.  It was informative.  Now my question is directed to the vi users 
out there.  Emacs has a feature to auto indent a file / line / section 
automatcially based on the syntax.  Is there a similar feature in vim?  
I've googled for a solution but haven't found anything similar to what 
I'm looking for.  Does anyone know if it exists and where to get it?  
Sorry Rob but vi is my friend and the only text editor I use.... ;-)
