Dimitri has released a new version of the doxygen source code documentation generator tool. http://www.stack.nl/~dimitri/doxygen/download.html#latestsrc
Created attachment 154019 [details] ebuild for 1.5.6 ebuild for 1.5.5 renamed for version 1.5.6 works. (see attachment)
Thanks for reporting. However, there is no point in attaching an ebuild when it just has to be renamed without any changes.
