Moving a lot of projects off GitHub

#!/bin/bash

# Script to set all origin URLs of all my projects in my workspace to the new 
# (forgejo) URL, replacing previous GitHub URLs. 

# Background: I keep all my active projects as subdirectories of the 
# directory `workspace`. You need to clone all the projects from GitHub to
# Forgejo **first**, before running this script; but this is simply done 
# through the Forgejo user interface. See
# https://www.journeyman.cc/blog/posts-output/2025-03-08-installing-forgejo/


# Variables in capitals you can think of as configuration -- you will want
# to change these to account for the difference between your setup and mine
