Re: [Axiom-developer] Re: noweb

Hello, is somebody so familiar with the documentation of noweb, to point 
exactly at a place in the documentation that says something about what 
noweb SHOULD do if it sees

  <<NOT DEFINED CODE CHUNK NAME>>

in either documentation or code chunk?

The only place where I think it would be necessary to escape <<  is if 
an = sign immediately follows the >> AND the << starts at the first 
column. In all other situations the line should be output by noweb 
literally and NO error message should occurs. Maybe a WARNING (to 
stderr) would be nice, but still errcode=0.
