Source Code for Module gavo.svcs.renderers

 1  """ 
 2  A manual registry of renderers. 
 3   
 4  Renderers are the glue between a core and some output.  A service is the 
 5  combination of a subset of renderers and a core. 
 6   
 7  Renderers are actually defined in web.grend, but we need some way to 
 8  get at them from svcs and above, so the registry is kept here.
