mustr

mustr is a command-line utility designed for managing multiple virtual environments for Python projects. It aims to simplify the process of creating, activating, and switching between different Python versions and their associated dependencies. The tool allows users to define project-specific environments, ensuring that each project has its own isolated set of packages. This isolation prevents conflicts between different project requirements and keeps the global Python installation clean.

The core functionality of mustr revolves around its configuration file, typically named `.mustr` within a project directory. This file specifies the Python version to be used for the environment and can include a list of required packages to be installed automatically upon environment creation. mustr leverages existing Python installations on the system and creates virtual environments in a designated location, typically managed by the tool itself.

To use mustr, a user might first initialize a new environment for a project. This involves running a command like `mustr init` within the project's root directory. Subsequently, activating the environment allows the user to install packages using `pip` and run Python scripts within that specific context. Switching between environments is also straightforward, typically achieved with a simple command that points to the desired project's environment. The tool's design emphasizes ease of use and automation for developers working on multiple Python projects simultaneously.
