Version numbering script
Found this script somewhere on the internet. It make's version control much more suitable in a LaTeX document. In this script, the version starts with V0.<number>. Each time you save, the number increases (like x+1).
\documentclass{article}
\newcounter{run}
\InputIfFileExists{\jobname.runs}{}{}
\stepcounter{run}
\usepackage{atveryend}
\usepackage{newfile}
\AtVeryEndDocument{%
\newoutputstream{runs}%
\openoutputfile{\jobname.runs}{runs}%
\addtostream{runs}{\string\setcounter{run}{\number\value{run}}}%
\closeoutputstream{runs}%
}
\begin{document}
Output: V0.\therun
\end{document}
