+description:         Create, modify, use and share virtual machine images;
+                     assemble and generate all associated files from templates.
+                     All assembled files can be accessed by vm-build scripts as
+                     shared directory in the build container, and/or
+                     can be written to directories, ISO- or VFAT-images.
+                     ISO/VFAT images are created so 'cloud-init' can recognize them.
+                     VM-Build are executed in LXC containers managed through libvirt.
