+      CLI Helpers is a Python package that makes it easy to perform common
+      tasks when building command-line apps. It's a helper library for
+      command-line interfaces.
+
+      Libraries like Click and Python Prompt Toolkit are amazing tools that
+      help you create quality apps. CLI Helpers complements these libraries by
+      wrapping up common tasks in simple interfaces.
+
+      CLI Helpers is not focused on your app's design pattern or framework --
+      you can use it on its own or in combination with other libraries. It's
+      lightweight and easy to extend.
+
+      What's included in CLI Helpers?
+
+      - Prettyprinting of tabular data with custom pre-processing
+      - [in progress] config file reading/writing
+
+      Read the documentation at http://cli-helpers.rtfd.io

+      Python interpreter, on the command line by executing Python scripts,

+      purpose is to make the development of software for convex optimization
+      applications straightforward by building on Python's extensive
+      standard library and on the strengths of Python as a high-level

+      Python Fire is a library for automatically generating command line

+
+      * Python Fire is a simple way to create a CLI in Python.
+
+      * Python Fire is a helpful tool for developing and debugging
+        Python code.
+
+      * Python Fire helps with exploring existing code or turning other

+
+      * Python Fire makes transitioning between Bash and Python easier.
+
+      * Python Fire makes using a Python REPL easier by setting up the
+        REPL with the modules and variables you'll need already imported

+
+      In some ways, Mezzanine resembles tools such as Wordpress that

+      form data, store products, and other types of content. But
+      Mezzanine is also different.  Unlike many other platforms that

+      Mezzanine provides most of its functionality by default. This
+      approach yields a more integrated and efficient platform.

+      Nevow - Pronounced as the French "nouveau", or "noo-voh", Nevow
+      is a web application construction kit written in Python.  It is
+      designed to allow the programmer to express as much of the view
+      logic as desired in Python, and includes a pure Python XML
+      expression syntax named stan to facilitate this.  However it
+      also provides rich support for designer-edited templates, using
+      a very small XML attribute language to provide bi-directional
+      template manipulation capability.
+
+      Nevow also includes formless, a declarative syntax for
+      specifying the types of method parameters and exposing these
+      methods to the web.  Forms can be rendered automatically, and
+      form posts will be validated and input coerced, rendering error
+      pages if appropriate.  Once a form post has validated
+      successfully, the method will be called with the coerced values.

+      Pexpect is similar to the Don Libes "Expect" system, but Pexpect
+      as a different interface that is easier to understand. Pexpect
+      is basically a pattern matching system. It runs programs and
+      watches output. When output matches a given pattern Pexpect can
+      respond as if a human were typing responses. Pexpect can be used
+      for automation, testing, and screen scraping. Pexpect can be
+      used for automating interactive console applications such as
+      ssh, ftp, passwd, telnet, etc. It can also be used to control
+      web applications via "lynx", "w3m", or some other text-based web
+      browser. Pexpect is pure Python. Unlike other Expect-like
+      modules for Python Pexpect does not require TCL or Expect nor
+      does it require C extensions to be compiled. It should work on
+      any platform that supports the standard Python pty module.

+      PLY is an implementation of lex and yacc parsing tools for Python.
+      In a nutshell, PLY is nothing more than a straightforward lex/yacc
+      implementation.  Here is a list of its essential features: It's
+      implemented entirely in Python; It uses LR-parsing which is
+      reasonably efficient and well suited for larger grammars; PLY
+      provides most of the standard lex/yacc features including support for
+      empty productions, precedence rules, error recovery, and support for
+      ambiguous grammars; PLY is straightforward to use and provides very
+      extensive error checking; PLY doesn't try to do anything more or less
+      than provide the basic lex/yacc functionality.  In other words, it's
+      not a large parsing framework or a component of some larger system.

+Subject: [PATCH] Allow test_period_of_repetition to be slow
+
+Recent versions of hypothesis default to a 200ms timeout, which wasn't
+enough for my Thinkpad X220 to run this test. I've increased the timeout
+for this single test to hopefully a reasonable amount for older
+hardware.
+

+Subject: [PATCH] gio-types.defs: change some enums to flags
+
+These flags types were originally incorrectly handled in glib as being
+enums.  That bug was fixed, but they're still enums here, leading to

+
+Change them to flags.

++ * \file   generators.i
++ * \author Seth R. Johnson
++ * \brief  Define generator/iterator for any type
++
++Example:
++\code
++    SETUP_GENERATOR( std::vector<Cell>::const_iterator )
++    ADD_GENERATOR( Mesh, cells,
++    std::vector<Cell>::const_iterator, Cell, beginCells, endCells)
++\endcode
++would be a method to add a \c cells generator method method to the Python class
++\c Mesh, when the C++ class \c Mesh has a \c std::vector<Cell> accessed through
++methods \c beginCells and \c endCells.
++
++The macro \c ADD_GENERATOR_P would be if the underlying storage were \c
++std::vector<Cell*> instead.
++
++Alternatively, for containers of regular objects that provide \c begin(), \c end(), and \c const_iterator, you can use the \c ADD_CONTAINER_ITERATOR macro:
++\code
++ADD_CONTAINER_ITERATOR( QuadratureSet )
++\endcode

+Subject: [PATCH] Fix building on Nix
+
+./configure.py tries to find dbus-python header in dbus-1 includedir
+obtained from pkg-config or from --dbus flag. Unfortunately, when supplied,
+it also uses the flag for locating dbus-1 headers. This fails on Nix,
+since every package is installed into its own immutable tree so we cannot
+use a single directory for both dbus-python and dbus-1. We can fix this by
+using pkg-config for finding dbus-python headers too.
+
+Additionally, the build system also tries to install the dbus support module
+to dbus-python tree. Often, it is possible to handle this in pkgconfig as well [1]
+but unfortunately, dbus-python does not export the moduledir in its pc file
+so I have decided to solve this with an extra configure flag.

+      pysqlite is a DB-API 2.0-compliant database interface for SQLite.
+
+      SQLite is a relational database management system contained in
+      a relatively small C library.  It is a public domain project
+      created by D. Richard Hipp.  Unlike the usual client-server
+      paradigm, the SQLite engine is not a standalone process with
+      which the program communicates, but is linked in and thus
+      becomes an integral part of the program.  The library
+      implements most of SQL-92 standard, including transactions,
+      triggers and most of complex queries.
+
+      pysqlite makes this powerful embedded SQL engine available to
+      Python programmers.  It stays compatible with the Python
+      database API specification 2.0 as much as possible, but also
+      exposes most of SQLite's native API, so that it is for example
+      possible to create user-defined SQL functions and aggregates
+      in Python.

+From bd5a5b58b438ff34d27781e28cd7fab93bfc9f3f Mon Sep 17 00:00:00 2001
+From: Maximilian Bosch <maximilian@mbosch.me>
+Date: Sat, 9 Mar 2019 23:26:30 +0100
+Subject: [PATCH] Don't use `which` implementation to find required executables
+
+Nix specific patch.
+
+Rather than relying on a global state, we set an absolute store path for
+all external dependencies to ensure their functionality.

+Without this patch `virtualenv --python=python2.7 .` fails with an
+error because it notices that the python readline.so is not in the
+same path as python2.7. I assume this is to avoid copying the wrong
+file on systems where it is possible to find incompatible libraries by
+accident. Adding "/nix/store" to the prefix fixes this problem.
+
+A sitecustomize.py is created in the virtualenv which makes libraries
+from the python specified by the --python argument available to the
+virtualenv. For example, this makes readline and sqlite3 available
+when a wrapped python is specified. If no --python argument is passed,
+it will only add the path to the python used when building
+`virtualenv`, which is the unwrapped python, so sqlite3 won't be
+available.
