+/* Use this file to list _all_ ENABLE() macros. Define the macros to be one of the following values:
+ *  - "0" disables the feature by default. The feature can still be enabled for a specific port or environment.
+ *  - "1" enables the feature by default. The feature can still be disabled for a specific port or environment.
+ *
+ * The feature defaults in this file are only taken into account if the (port specific) build system
+ * has not enabled or disabled a particular feature.
+ *
+ * Use this file to define ENABLE() macros only. Do not use this file to define USE() or macros !
+ *
+ * Only define a macro if it was not defined before - always check for !defined first.
+ *
+ * Keep the file sorted by the name of the defines. As an exception you can change the order
+ * to allow interdependencies between the default values.
+ *
+ * Below are a few potential commands to take advantage of this file running from the Source/WTF directory
+ *
+ * Get the list of feature defines: grep -o "ENABLE_\(\w\+\)" wtf/FeatureDefines.h | sort | uniq
+ * Get the list of features enabled by default for a PLATFORM(XXX): gcc -E -dM -I. -DWTF_PLATFORM_XXX "wtf/Platform.h" | grep "ENABLE_\w\+ 1" | cut -d' ' -f2 | sort
