+Obviously, `Argh` is not the only CLI helper library in the Python world.
+It was created when some similar solutions already existed; more appeared
+later on. There are valid reasons behind maintaining most projects.
+The list below is nowhere near exhausting; certain items are yet to be
+reviewed; the comments should have been more structured. However, it gives
+a picture of the alternatives.
+Ideally, we'd need a table with the following columns: supports argparse;
+has integrated parser; requires subclassing; supports nested commands;
+is bound to an unrelated piece of software; involves "magic" (i.e. undermines
+clarity); depends on outdated libraries; has simple API; has unobtrusive API;
+supports Python3. Not every "yes" in this table would count as pro.
+* argdeclare_ requires additional classes and lacks support for nested
+* argparse-cli_ requires additional classes.
+* django-boss_ seems to lack support for nested commands and is strictly
+* entrypoint_ is lightweight but involves a lot of magic and seems to lack
+ support for nested commands.
+* opster_ and finaloption_ support nested commands but are based on the
+ outdated `optparse` library and therefore reimplement some features available
+ in `argparse`. They also introduce decorators that don't just decorate
+ functions but change their behaviour, which is bad practice.
+* simpleopt_ has an odd API and is rather a simple replacement for standard
+ libraries than an extension.
+* opterator_ is based on the outdated `optparse` and does not support nested
+* clap_ ships with its own parser and therefore is incompatible with
+* plac_ is a very powerful alternative to `argparse`. I'm not sure if it's
+ worth migrating but it is surely very flexible and easy to use.
