-Subject: [PATCH] Look for caja extentions at $CAJA_EXTENTSION_DIRS
-
-CAJA_EXTENSION_DIRS is a list of paths where caja extensions are
-looked for. It is needed for distributions like NixOS that do not
-install all extensions in the same directory. In NixOS each package is
-installed in a self contained directory.
