I removed yap from [community] as it's unmaintained (both upstream and in Arch) and doesn't build with GCC 5.1. Though a fix exists in a mailing list post upstream, I encountered further issues with its Java bindings and building its texinfo documentation. If anyone wants to put it back in [community], you'd have to fix the build issues and then adopt it after uploading new packages. Users are welcome to upload it to the AUR as well. PKGBUILD is available from the following URL: https://projects.archlinux.org/svntogit/community.git/tree/trunk/PKGBUILD?h=packages/yap&id=0a0cc38daec2
