Re: How to get warnings for unused parts of a file?

[Leo Correia de Verdier]

There might be more elegant ways to do it (there probably is), but I have a 
variable I define in my output files, is-loaded-file and then I can use #(if 
(defined? 'is-loaded-file) … ) in the definition files to test. This requires a 
situation where there’s a clear separation between ”definition files” and 
”output files”, but works quite well for me.
