****************************

The modules described in this chapter have been superseded by other
modules for most use cases, and are retained primarily to preserve
backwards compatibility.

Modules may appear in this chapter because they only cover a limited
subset of a problem space, and a more generally applicable solution is
available elsewhere in the standard library (for example, "getopt"
covers the very specific task of "mimic the C "getopt()" API in
Python", rather than the broader command line option parsing and
argument parsing capabilities offered by "optparse" and "argparse").

Alternatively, modules may appear in this chapter because they are
deprecated outright, and awaiting removal in a future release, or they
are *soft deprecated* and their use is actively discouraged in new
projects. With the removal of various obsolete modules through **PEP
594**, there are currently no modules in this latter category.

* "getopt" --- C-style parser for command line options
