setup.sh

#!/bin/bash

# ------------------------------------------------------------------------
# This is the setup.sh script for the dev-cli project.
# It is used to set up the environment and install dependencies for the dev-cli
# command-line tool. The script performs the following tasks:
# - Checks if Python 3 and the venv module are installed.
# - Creates a virtual environment (venv) to isolate the project's dependencies.
# - Installs all required dependencies from requirements.txt or setup.py.
# - Installs the dev-cli package globally in editable mode.
# - Ensures that the dev-cli tool is available for use in any directory.
