First of all thank you for the work. I am interested to package the $summary package for kde herd as it is needed for nepomuktvnamer. Your mentor tampakrap pointed me to your overlay, that there is a ebuild already. So i had a look at it and find some small things, that have to be changed before pushed to the kde overlay and later on to main tree. - The description should reflect thats a KDE based library not pure Qt one, maybe something like "KDE-based library to fetch TV series information from thetvdb.com" - SRC_URI should use mirror://sourceforge/ - kde4-base eclass provides a debug mode, so the debug use flag should be added - cmake searches for doxygen to generate a small info page for the sourceforge project page. This is only needed for the author of the project. This means you can disable it via cmake parameter in src_configure. Last but not least, its up to you: Are you interested to co-maintain the package?
Nepomuk is going to be dead.
