# remove-repo.sh: Git Repository Removal Script
#
#  Description:
#  This script removes specified Git repositories from the user's local
#  directories ($HOME/local/github and $HOME/local/git) and any associated
#  symbolic links in the home directory. It checks if the directory is a Git
#  repository before removing it. Includes a dry-run mode for simulation.
