[texhax] Reverse page numbering(begin with the last page number and end with 0)

[Othmane Benkirane]

Thank you very much for your help
Your solution did not work (it showed the opposite of the page), but with some tests, I ended up with something working:

\documentclass{article}
\usepackage{refcount}
\usepackage{lastpage}
\newcounter{mypage}

\usepackage{fancyhdr}
\pagestyle{fancy}
\fancyhf{}
\cfoot{\setcounterpageref{mypage}{LastPage}\addtocounter{mypage}{-\thepage}\themypage}

\begin{document}
abc\newpage cd\newpage ef\newpage gh
\end{document}

Thank you very much,
Othmane Benkirane.
