Re: Spurious warning from require'd package

I still don't fully understand, but I got rid of my warning...
Writing helps reading as usual.
I noticed that the line I needed my require for was the definition of an object which was itself not used.
So, I could remove both, and the warning went away.

I am still interested in explanations and advices, though.

Thanks. Somehow, the name that was reported as used only once should not have been "ClearCase::Argv" (the class name), but rather this of the object of that type, which was created and then not used anymore (after I had removed some code). But otherwise, the warning was useful and spotted a real, if minor, issue. Marc	[reply]
