An improved shell command for Flask

Flask-Konch adds an improved shell command, flask konch, to the Flask CLI.

Benefits of flask konch over flask shell

• Uses IPython, BPython, or ptpython if available, and falls back to built-in interpreter

• Automatically imports top-level Flask functions and classes by default

• Define additional variables to include in the shell context

• Configurable banner and prompt

Flask-Konch uses konch, a shell configuration utility, under the hood.
