+# Description:
+# This simple script shows how to modify the content of a feature manager
+# data file.
+# 
+#
+
+use strict;
+use FMCreate;
+
+#
+# Hardwire the datafile - this is only an example.
+# 
+my $datfile = "features.dat";
+my $datfile2 = "features2.dat";
+my $datfile3 = "features3.dat";
+
+#
+# Create an object that represents a feature data file.
+#
+my $fmc = FMCreate->new();
+
+#
+# Load the content of the data file into our FMCreate object.
+# Note that this will die if the content does not seem to be a feature set
+# file. This can happen if the first four bytes aren't 'feat' or if reading
+# the file fails at any point. This will also happen if the file is the wrong
+# size.
+#
+$fmc->LoadUp($datfile) or die "Failed to load up data from '$datfile'\n";

+#
+# Get feature flag '0x10000009'

+
+#
+# Change the feature flag.. Note that the feature flag object '$ff' is a
+# reference to the feature flag in '$fmc' - it's still in there, so when
