There have been enough of these in my information river lately that they have risen above the threshold of ‘annoying but ignorable’, so let me state for the record:
If you are importing libraries and you aren’t counting those libraries in your ‘Lines of Code’ claims, you are a liar.
And, as a corollary, claims that the program that does all the work in imported libraries (particularly ones that you didn’t write) is somehow ‘better’ than the one that doesn’t are just snake oil.
