We generate one current and multiple historical-reports which are linked to each other.
Historical reports are created in a subfolder, so the final folder structure of the reports looks sort of like this:

reportdir/historical1/historical.html
reportdir/historical2/historical.html
reportdir/index.html
reportdir/all-pkgs.html
[...]

hrefs of links in these files contain windows-backslashes instead of simple slashes - this makes problems when putting the files on a server.
I found wrong hrefs at least at the following places:
1) all-pkgs.html: link to historical.html - backslash should be a slash

<a target="classPane" href="historical1\historical.html">

2) historical.html: links to sources: backslash should be deleted here

<a target="classPane"  href="..\/de/tolina/SomeClass.html"  title="de.tolina.SomeClass">
