+#!/bin/bash
+# $Id$
+#
+#
+#  To use this script you need
+#  - a Linux system >=2.4 with libc >=2.2.*
+#  - the valgrind debugger (http://www.valgrind.org/)
+#  - lots of memory (RAM + swap space > 600MB!) and
+#  - a fast computer =or= a lot of patience.
+#
+#  It is useful (but not required) to compile FlightGear without
+#  any optimizations (-O0 without -funroll-loops etc.). Otherwise
+#  the debug messages might not seem to make sense in some cases.
+#
+#  The sample suppression file is designed for a SuSE 7.1 system
+#  with Linux 2.4.18, XFree86 4.2.0 and a 3dfx card. Don't use it
+#  as it is, but create your own! You will likely have different
+#  libraries with different bugs.
+#
+#  If you have problems with valgrind and FlightGear, don't bother
+#  the valgrind author -- ask on the flightgear-devel list first!
+#
+#
+# 
+#  adapt the following two entries to your needs:
+#
