When yo LaTeX a file for the first time, or (sometimes) after LaTeX
produced an error, there will be many undefined citations in your text,
one for every \cite{...} which is not defined in the .aux file.
Thus you get loads of "Citation `...' on page ... undefined" warnings
which clobber your screen and .log file.
I made a style file which will cause LaTeX to warn only once for every
undefined citation. It's rather simple, but useful, so I decided to post
it here.
Regards, Nico.
