+#!/bin/bash

+# This scripts reads include/freerdp/settings.h and scans the
+# rdp_settings structure for all the fields until the /END of ABI
+# stable zone/ comment.  It then generates a set of #define one per
+# non-padding field, valued as the index of the field, taking into
+# account padding fields.  These field #defines are updated in that
+# same file.
+#
+# Usage:
+#
+#    cd $freerdp_source_directory
+#    scripts/update-rdpSettings
