\section{The \texttt{invoice} Package}
The \texttt{invoice} package was conceived in late 2000
when the author had to dig through a truly aweful pile
of expense bills without having a \LaTeXe-capable
spreadsheet (or any spreadsheet) available. After several
miscalculations with a pocket calculator due to forgotten
entries or double entries the idea came up to have \LaTeXe\
do the calculation work. As such, the package in its present
stage is highly specialized with regard to the documents it
generates. The \texttt{invoice} package is basically a
tailor-made solution for a consultant who charges fees and
claims all sorts of expenses, sometimes working on different
assignments for the same client.
Comments and suggestions are highly welcome and
should be directed to the author at
\texttt{corff@zedat.fu-berlin.de} or
\texttt{oliver.corff@email.de}.
The \texttt{invoice} package is put under the GNU
Public Licence.
