        Light-weight project manager for Python projects.
        
        This is a tiny tool built to automate repetitive manual tasks, when creating a new Python development project and managing project dependencies. What you will end up with, when using *jetzt*?
        
        1. A new **project directory** under your *current directory*.
        1. A new *virtualenv* named `venv` under the project directory with the System-level installed Python 3.6+ version.
        1. The virtualenv will have `pip` and `setuptools` installed and updated to latest available versions.
        1. Additional packages will be installed based on the selected project type.
        1. Depending on the project type, other resources may be created to initialize a new project.
        
        ## Prerequisites
        
        This has been tested on the following setup:
        
        1. MacOS Sierra 10.12.6 and newer
        1. Python 3.6+ (installed via *Homebrew*)
        1. Zsh shell (with oh-my-zsh)
        
        Things should probably work nicely on other releases of macOS and on various Linux distros too. **Python 3.6+ and zsh are expected.**
        
        [A changelog](https://github.com/janikarh/jetzt/blob/master/CHANGELOG.md) is maintained.

        ## Create new project
        
        Run `jetzt --scaffold` in the directory, where you want to place your project directory, and follow the prompt.
        
        ### Scaffolding options
        
        You have couple of options for a new project.
        
        Each project will have the following packages installed as *development dependencies*:
        
        - flake8
        - pytest
        - jetzt
        
        These will be listed in `requirements-dev.txt`.
        
        A metadata file `jetzt_metadata.json` is maintained, and this will be used to manage the project metadata, including installed dependencies. This should be committed to git along with the rest of the project files.
        
        #### Python - [Blank]
        
        This scaffolding option is meant to be a good starting point for a generic Python project. This option will not install any additional packages.
        
        #### Python - Flask
        
        This scaffolding option is meant to be a good starting point for a new Flask-based webapp / API project. This option will install the following packages:
        
        - Flask
        
        These will be listed in `requirements.txt`.
        
        #### Python - Jupyter
        
        This scaffolding option is meant to be a good starting point for a new data science / analytics project. This option will install the following packages:
        
        - jupyter + ipykernel
        - pandas
        - matplotlib
        - seaborn
        
        These will be listed in `requirements.txt`.
        
        Also a `data`-directory will be created, and [this notebook](https://github.com/janikarh/jetzt/blob/master/jetzt/seeds/python_jupyter/starting-point.ipynb) will be copied to the project root (the notebook is included in the installation package).
        
        After scaffolding, start a jupyter server by running `jupyter-notebook` in the project root directory.
        
        ## Manage Python dependencies
        
        All dependency management takes place in a *virtualenv* (created with `jetzt --scaffold`), so **make sure you have activated the project's environment before running these commands with `source venv/bin/activate`**. There is naturally the standard way of using *pip* to install dependencies, and manually add them to `requirements.txt`, etc.
        
        *Jetzt* includes an option to install and manage the dependencies for you. Please continue reading.
        
        ### Install a dependency
        
        To install a package `requests`, run `jetzt --install` and follow the prompt. You have an option to install the package as *a production dependency* or as *a development dependency*. What does all this mean, you might ask? Jetzt will:
        
        1. Install the package *requests* (latest available version).
        2. Add the package `requests` to `requirements.txt` with a version requirement set to minimum of the currently installed version. The packages, which *requests* depends on, are *not* added. If you selected `DEV` as a dependency type, the file `requirements-dev.txt` will be used instead.
        
        **At the moment, you can only install one package at a time.**
        
        Example of `requirements.txt`:
        
        ```
        requests>=2.21.0
        ```
        
        **Version pinning:** To install a specific version of a package, add the version, just as you would with pip. For example: `requests==2.20.1`. This will pin the version in `requirements.txt` like so:
        
        ```
        requests==2.20.1
        ```
        
        ### List installed dependencies
        
        To list installed dependencies, run `jetzt --list`.
        
        
        ### List outdated dependencies
        
        To list outdated dependencies, run `jetzt --outdated`.
        
        ### Update outdated dependency
        
        To update an outdated dependency, run `jetzt --update`. This will allow you to choose an outdated dependency to update. After the update, the command will update the outdated dependency list automatically.
        
        ### Remove installed dependency
        
        To remove an installed dependency, run `jetzt --remove`. This will list all installed dependencies, and let's you choose which one you want to remove. After the update, the command will update the outdated dependency list automatically.
        
        ### Reinstall all dependencies
        
        To reinstall all dependencies (excluding editable), run `jetzt --reinstall`. The dependency versions are pinned temporarily for installation, so yo will end up with the same version as before the reinstallation. *Make sure, you are in active virtualenv.*
        
        ### Create requirements files
        
        Run `jetzt --create-requirements` to generate standard `requirements.txt` and `requirements-dev.txt` based on `jetzt_metadata.json`.
