+%description
+mergerfs is similar to mhddfs, unionfs, and aufs. Like mhddfs in that it too
+uses FUSE. Like aufs in that it provides multiple policies for how to handle
+behavior.

+* Sat Sep 05 2015 Antonio SJ Musumeci <trapexit@spawn.link>
+- Include PREFIX to install
+
+* Mon Dec 29 2014 Joe Lawrence <joe.lawrence@stratus.com>
+- Tweak rpmbuild to archive current git HEAD into a tarball, then (re)build in
+  the rpmbuild directory -- more complicated but seemingly better suited to
+  generate source and debug rpms.
+
+* Fri Jun 20 2014 Joe Lawrence <joe.lawrence@stratus.com>
+- Initial rpm spec file.
