Dear Maintainer,

I noted the current ACM-6.0+ package is lacking of all the documentation
available from the original package, more specifically:

- The user manual available under doc/manual. Without this manual, the bare
  executable can hardly be used.

- The navigation charts in PDF format available under doc/charts. These charts
  have been generated by several programs and Bash scripts available under
  the directory "tools"; data come from several sources and are partially
  edited by hand to generate the sceneries and the charts. Although possibly
  outdated and incomplete, it's still an useful starting base to learn the basic
  techniques of aerial navigation.
