+# This script is designed to remove all non-API global symbols from an object
+# file. The only global symbols that should be retained are those that belong
+# to the official namespace. Unfortunately doing this is platform-specific, as
+# the object file manipulation tools are not consistent across platforms.
+#
+# On platforms where this script does not know what to do, the object file
+# will retain non-API global symbols, and this may have unpleasant side effects.
+#
+# Prefixes that belong to the official namespace are:
+#	ast_
+#	_ast_
+#	__ast_
+#	astman_
+#	pbx_
