\section{Revision History}
\label{app:history}
This section contains a verbatim revision history taken from the \imager{} code. 
Except for minor typos or cosmetic changes, each modification in the 
code is documented by 1 line of code that includes three informations:
\begin{itemize}
\item The language revision number of the affected command
\item the date of the revision
\item a short description of the change
\end{itemize}
\imager{} only gives the major revision number at start of program.
The individual revision numbers of all its languages can be obtained
using command \qom{SIC VERSION}.
This information can be useful for users encountering a suspected
bug or strange behaviour, allowing him/her to see whether the problem
has been handled since the version of \imager{} they use.
