# replicate-file.sh
#
# DESCRIPTION:
#
# This is a script that will update all copies of a reusable file
# from one master file, specified on the command line.
# The primary use case is for updating one module into many projects.
#
# USAGE:
#
# To replicate <file> to all copies found in the projects directory:
#       ./replicate-file.sh <file>
#
# CONFIG:
#
# An optional config file can be created as ~/.getgodot.conf. This
# file is shared with Shine Upon Thee's godot.sh (Get Godot) script.
# Set the project path to search for replicants with this:
#       PROJECTPATH=/path/to/projects
#
# NOTES:
#
# This script is written and maintained by Dana Olson of Shine Upon Thee
# http://www.shineuponthee.com/
# 
# https://github.com/adolson/godot-stuff/blob/master/replicate-file.sh
# https://raw.githubusercontent.com/adolson/godot-stuff/master/replicate-file.sh
#
# It is licensed under the X11/Expat/"MIT" terms (whatever the Godot Engine uses)
#
# CHANGELOG:
#
# 1.0 - initial release
# 1.1 - verbiage fixes
# 1.2 - link fix, renamed script
