+In src/tagmanager/tm_parser.c:
 Add a map_FOO TMParserMapEntry mapping each kind's letter from foo.c's
 FooKinds to the appropriate TMTagType, and add the corresponding
 MAP_ENTRY(FOO) to parser_map.
 (You may want to make the symbols.c change before doing this).
 
+In src/tagmanager/tm_parser.c:
+Update tm_parser_context_separator() and tm_parser_has_full_context() to
+handle the new parser if applicable, by adding a TM_PARSER_FOO case entry.
+
 In filetypes.c, init_builtin_filetypes():
 Set the 2nd argument of the FT_INIT() macro for this filetype to FOO.
