5.14.9. What if I just want to print it?

If you don't want to write code to any output file, just use a tangler with a null sink device. That device just throws away all the data written to it. For example:
Start C section to null sink[1 /4 ] Next Last
     1: #line 128 "faq.ipk"
     2: @from interscript.tanglers.c import c_tangler
     3: @from interscript.drivers.sinks.null import null_sink
     4: @dummy = c_tangler(null_sink(), weaver)
     5: @select(dummy)
     6: /* These comments do not get written out */
End C section to null sink[1]
