+# This script applies patches to the UnrealEngine repository.
+#
+# We don't keep our own unreal engine repository because that
+# would be overkill.  Instead, you must check out the standard
+# copy of Unreal engine, then we apply a few simple patches.
+# The files patched are:
+#
+#   UnrealEngine/Engine/Saved/UnrealBuildTool/BuildConfiguration.xml
+#   UnrealEngine/Engine/Source/Runtime/Core/Private/Logging/LogMacros.cpp
+#
+# This python program will generate these files as necessary.
+#
+# It is safe to run this patch program a second time to repair
+# any of these files, if necessary.  Doing so will not corrupt
+# anything.
