# --------------------     Change Versions Tool (cv)    ------------------------------
# 1. The Change Versions Tool (cv) is a Bash script designed to simplify the process of changing versions in an Odoo development environment. It automates the process of switching the codebase to a specific branch in both the Odoo and Odoo Enterprise repositories, updates the virtual environment, and provides clear feedback on the results. This tool is especially useful for developers working with different versions of Odoo.
