+ */
+
+/******
+
+  This file contains the list of all CSS properties that are just
+  aliases for other properties (e.g., for when we temporarily continue
+  to support a prefixed property after adding support for its unprefixed
+  form).  It is designed to be used as inline input through the magic of
+  C preprocessing.  All entries must be enclosed in the appropriate
+  CSS_PROP_ALIAS macro which will have cruel and unusual things done to
+  it.
+
+  The arguments to CSS_PROP_ALIAS are:
+
+  -. 'aliasname' entries represent a CSS property name and *must* use
+  only lowercase characters.
+
+  -. 'id' should be the same as the 'id' field in nsCSSPropList.h for
+  the property that 'aliasname' is being aliased to.
+
+  -. 'method' is the CSS2Properties property name.  Unlike
+  nsCSSPropList.h, prefixes should just be included in this file (rather
+  than needing the CSS_PROP_DOMPROP_PREFIXED(prop) macro).
+
+  -. 'pref' is the name of a pref that controls whether the property
+  is enabled.  The property is enabled if 'pref' is an empty string,
+  or if the boolean property whose name is 'pref' is set to true.
