Compile shader command missing with Pixar Renderman 21.6

#1

I’m doing a tutorial using RSL but the shader compiler its missing.
I’m using the 21.6 NC version
Is there a reason why?
I notice that there is a new command oslc
Is this the new way using OSL’s is there a tutotial writing OSL and importing them as digital assets in Houdini.
thanks in advance,
-Alex
