7This is a citation for the 5\deg. The citation should be known \cite{known}.
8We follow this with an unknown citation \cite{unknown}.

10To test various combinations we need to cite more than one author.  To this
11end, I cite two known authors \cite{known,known2}.  This might include one
12known and one unknown \cite{unknown,known}.  Another bizarre case might be
13one known, one unknown and another known \cite{known,unknown,known2}.

15Need to have a test for \verb#\cite# commands that span multiple lines \cite{
16known,%
17%  very long comment that has some utility
18known2} (which has two comment lines in a row!) and one final test \cite{%
19known, %
20known2%  some jabbering
21}.
