# @author Erodozer <ero@erodozer.moe>
#
# Simple Bach Script that fetches and merges standard godot addon repositories from github
# to your project.  You can use this instead of Godot's Asset Library if you wish to
# include dependencies in your projects while developing, but not include them in your git.
#
# Run this from the root directory of your project
#
# It parses a json file called godot_packages.json with the following schema
#
# [
#   {
#     "git": "<user>/<repo>",
#     "branch" ?: string, # main is the default
#     "tag" ?: string, # only set this if you want to lock to a specific published version
#   },
#   ...
# ]
# 
# Downloaded addons are merged into your project's addon's folder.
# If the addon as a LICENSE file in the root of the repo, it is copied to the addon's nested folder
# .gitignore files are also added to the nested folder.
#
#
# Requires:
#   unzip
#   jq
#   wget
