+I18N
+----------------------------------------------------------------------
+
+We support i18n (gettext anyhow) in the library.
+
+However many messages come from the daemon, and we don't translate
+those at the moment. One reason is that the appliance generally has
+all locale files removed from it, because they take up a lot of space.
+So we'd have to readd some of those, as well as copying our PO files
+into the appliance.
+
+Debugging messages are never translated, since they are intended for
+the programmers.
+
+Extended printf
+----------------------------------------------------------------------
+
+In the daemon code we have created custom printf formatters %Q and %R,
+which are used to do shell quoting.
+
+%Q => Simple shell quoted string. Any spaces or other shell characters
+ are escaped for you.
+
+%R => Same as %Q except the string is treated as a path which is prefixed
+ by the sysroot.
+
+eg.
+
+asprintf (&cmd, "cat %R", path);
+==> "cat /sysroot/some\ path\ with\ spaces"
+
+Note: Do NOT use these when you are passing parameters to the
+command{,r,v,rv}() functions. These parameters do NOT need to be
+quoted because they are not passed via the shell (instead, straight to
+exec). You probably want to use the sysroot_path() function however.
