When typing in an incorrect subcommand for a [tcc4tcl::new] created handle the error message does not contain the complete list of subcommands as described in the high-level API page.

% set handle [tcc4tcl::new]
% $handle ?
unknown or ambiguous subcommand "?": must be cproc, linktclcommand, code, tk, or go

It seems to be missing cwrap, ccode, add_include_path, add_library_path, and add_library.
