+
+;;; Commentary:
+
+;; The default GTK file selection dialog is not sufficient for our
+;; needs. Limitations include:
+;;
+;; - not derived from GtkDialog
+;; - no support for filters based on file types
+;; - no support for setting an initial directory
+;; - no way to tell it 'file must exist'
+;; - no easy way to tell it to look at directories only
+;; - ugly as sin
+;;
+;; This attempts to rectify the situation.
