INSTALL_FILES: sshkeysfiles/manifest
+ All variables starting INSTALL_FILES are considered, and are processed in
+ alphabetical order, so if INSTALL_FILES, INSTALL_FILES_distbuild and
+ INSTALL_FILES_openstack are given, manifests in INSTALL_FILES are processed
+ before those in INSTALL_FILES_distbuild, followed by INSTALL_FILES_openstack.
+
+ Multiple manifest files may be given in the same INSTALL_FILES variable,
+ by providing a whitespace separated list.
+
+ Shell word splitting is supported, so if a manifest's path has spaces in,
+ the path may be shell escaped.

More generally entries in the manifest are formatted as:
[overwrite] <octal mode> <uid decimal> <gid decimal> <filename>
