+OSTree is a tool for managing bootable, immutable, versioned
+filesystem trees. While it takes over some of the roles of tradtional
+"package managers" like dpkg and rpm, it is not a package system; nor
+is it a tool for managing full disk images. Instead, it sits between
+those levels, offering a blend of the advantages (and disadvantages)
+of both.
