As I'd mentioned earlier, Google code has added a Wiki feature supposed to be useful to maintain documentation. We in the programming world know that once you document stuff in a place other than the original source code, it rapidly goes out of sync. So I tried another way to present the generated muSE documentation right where the source code is available - the Subversion repo itself.
I simply generated the HTML documentation using doxygen and placed the output into its own Subversion module/folder - here. Once all the files are tagged with the appropriate mime types, the whole site is functional .. and versioned to boot!
Here are the mime-type setting commands you need to use in the doxygen generated documentation folder -
svn propset svn:mime-type "text/html" *.html
svn propset svn:mime-type "image/png" *.png
svn propset svn:mime-type "text/css" *.css
svn propset svn:mime-type "image/gif" *.gif
svn propset svn:mime-type "text/plain" *.md5
svn propset svn:mime-type "text/plain" *.map
