Valhalla is a utility that makes it super easy to share files and screenshots over the web. This is achieved through the following features:

• Valhalla is easily extensible to support your favourite services
• Keeps track of all your files
• Convenient screenshot binary: Just map your printscreen key to valhalla-screenshot and we'll do the rest
• Neat and tidy UI

On RHEL-like systems:

dnf copr enable bob131/valhalla
dnf install valhalla

hub clone Bob131/valhalla
./autogen.sh
make

Try making a symbolic link from the build folder to your XDG_DATA_HOME:

ln -s `pwd`/src/modules/.libs ~/.local/share/valhalla
