  \033[0m\033[4mhttps://www.veen.world/\033[0m

\033[1mOverview:\033[0m
A configurable Python tool to manage multiple repositories via a unified command-line interface.
This tool automates common Git operations (clone, pull, push, status, etc.) and creates executable wrappers and custom aliases to simplify your workflow.

\033[1mFeatures:\033[0m
  • \033[1;33mAuto-install & Setup:\033[0m Automatically detect and set up repositories.
  • \033[1;33mGit Command Integration:\033[0m Execute Git commands with extra parameters.
  • \033[1;33mExplorer & Terminal Support:\033[0m Open repositories in your file manager or a new terminal tab.
  • \033[1;33mComprehensive Configuration:\033[0m Manage settings via YAML files (default & user-specific).

For detailed help on each command, use:
