doxygen.css and GPL

[Thorsten Schöning <ts...@am-soft.de>]

Hello,

I'm now able to generate apidocs using doxygen and the maven build
scripts and recognized, that there's some code to replace the
doxygen.css and tabs.css with almost unusable style definitions. The
comment says something about GPL, but the original files don't seem
to have any GPL statement (anymore?) and on the Doxygen homepage
itself one can find the following sentence:

> Documents produced by doxygen are derivative works derived from the
> input used in their production; they are not affected by this
> license.

To me this reads like we can simply remove the changes to the
stylesheets and use the original ones, am I correct? Else I ask myself
why we don't need to change the JavaScript files and maybe images,
too. The docs look really ugly without those stylesheets.

Following is the code used to replace the file contents:

<!--  doxygen.css is GPL'd, looks better with it, but not intolerable without it -->
<echo file="${target.dir}/site/apidocs/doxygen.css">
        /*
        &license;
        */
        /*  Minimal replacement for GPL'd doxygen.css  */
</echo>
<echo file="${target.dir}/site/apidocs/tabs.css">
        /*
        &license;
        */
        /*  Minimal replacement for GPL'd tabs.css  */
        DIV.tabs {
                display : none ;
        }
</echo>

Mit freundlichen Grüßen,

Thorsten Schöning

I read this the same way.  I believe APR is using the default
doxygen.css: http://apr.apache.org/docs/apr/1.5/doxygen.css

That said, Christian, what's the ASF party line here?
