+This patch distinguishes between the data directory path for GUI and the one
+for non-GUI by allowing to set the former path.
+
+highlight package has two outputs: out and gui.  Both outputs have files which
+will be in the same directory /share/highlight/ without this patch (see also
+install and install-gui tasks in makefile).  In the gui's data directory,
+there are GUI specific files in /share/highlight/gui-files/{l10n,ext}/.
