How to get docstring of a function ?

[Pablo Winant]

Hello,

I would like to programmatically read the docstring of a .m function, as 
in :

s = help('randn')
... then process s

This works in Matlab, but in octave it triggers an interactive viewer 
which I don't want (I try to control Octave remotely).

Is there another command/procedure for it ?

Best,

Pablo
