Except that the "commented out" bits have their own syntactic structure.
Ideally, a shell script here document as argument to awk ought to be
parsed in AWK Mode.  The non-code bits of literate programming are also
likely to have their own structure.  CPP sections are handled as
C/C++/ObjC, but the complication caused by keeping them separate from
the main code are considerable.
