Hi all,

@Bernhard, Thank you again for testing this patch!

@Jon, This is the file format of the manualpages configuration:

[cgi basename]=[path/to/page]

For example:

 > BASE_URL=https://wiki.ipfire.org
 > index=configuration/system/startpage

Results in "index.cgi" linking to "https://wiki.ipfire.org/configuration/system/startpage".
Please note that the path does not start with a slash, because the get_manualpage_url function always adds one between the base url and the path.

Unfortunately, I couldn't figure out how to include all this in the installer and I need help with that.
So I would suggest we wait until this has been approved and integrated.

Regards,
Leo
