The description says

The conversion codes 's#' and 't#' will output Py_ssize_t
if the macro PY_SSIZE_T_CLEAN is defined before Python.h
is included, and continue to output int if that macro
isn't defined.

which (IMO, of course), specifies precisely what PY_SSIZE_T_CLEAN
does. What information do you find lacking here?
