NAME
briefcase - Tool for converting Python projects into standalone native
applications for distribution.

SYNOPSIS
briefcase [command] [platform] [format] [options]

DESCRIPTION
briefcase is a tool that allows you to convert a Python project into a
standalone native application, ready for distribution. It supports multiple
platforms and formats, making it easy to create, build, and publish applications.

USAGE
briefcase [-h] <command> [<platform>] [<format>] [...]

ENVIRONMENT SETUP
Before using Briefcase, you need to prepare your environment. This involves
ensuring Python is installed and setting up a virtual environment.

  1. Install Python
Briefcase requires Python to be installed on your system. You can use the
system's default Python or manage multiple Python versions using pyenv.
Option 1: Use the system Python
Most Linux distributions and macOS come with Python pre-installed. To check
if Python is installed, run: python3 --version
If Python is not installed, you can install it using your system's package
manager. For example:
   - On Debian/Ubuntu: sudo apt install python3
   - On macOS (using Homebrew): brew install python
Option 2: Use pyenv to manage Python versions
If you need to use a specific version of Python or manage multiple versions,
you can use pyenv. To install pyenv, follow the instructions at:
https://github.com/pyenv/pyenv
After installing pyenv, you can install a specific Python version,
for example:
   pyenv install 3.9.7
And set it as the global version:
   pyenv global 3.9.7

  2. Create a Virtual Environment
It is recommended to use a virtual environment to isolate your project's
dependencies. To create and activate a virtual environment, follow these steps:
1. Create a virtual environment:
   python3 -m venv venv
2. Activate the virtual environment:
   - On Linux/macOS: source venv/bin/activate
   - On Windows: venv\Scripts\activate
Once activated, your terminal prompt will change to indicate the virtual
environment is active. You can now install Briefcase and other dependencies
within this environment.

OPTIONS
      -h, --help
               Show this help message and exit.
      -V, --version
               Show the program's version number and exit.

EXAMPLES

  briefcase new
The `briefcase new` command requests basic information to create a
new application. The following details are required:
      Formal Name: Full name of the application (default: "Hello World").
      App Name: Technical name of the application, without spaces (default: "helloworld").
      Bundle: Unique app identifier. If you own a domain, enter it in reverse
         order (e.g., com.example). Otherwise, use the default (com.example).
      Project Name: Name of the project directory (default: "Hello World").
      Description: Brief description of the application (accept the default or customize).
      Author: Your name as the author of the project.
      Author's Email: Your email, used for settings and publishing.
      URL: Application home page (use your own domain or the default https://example.com/helloworld).
      License: Choose the project license (default: BSD).
      GUI Framework: Choose the GUI framework (default: Toga, BeeWare's GUI toolkit).

  briefcase create
This command installs the dependencies specified in the  pyproject.toml
file, creating the project structure for the native operating system
and configuring the necessary files for packaging and distributing the application:
(venv-venv)$ briefcase create

        ...
`briefcase create android` This command configures the project structure for
packaging on the Android system.

  briefcase build
The command compiles and prepares a Briefcase project for
distribution on the specified platform. It generates the binaries, packages and
configurations required to run the application
(venv-venv)$ briefcase build
