# This creates the conditions for testing Michael Haggerty's "git imerge",
# as described in https://wilsonmar.github.io/git-imerge 
#
# Before running this, copy this file to the folder where you want the test repo created,
# then chmod 555 git-imerge-test-create.sh
# Running this creates a folder above the script folder
# and creates a file named somefile.md in both the master branch and "feature1" branch.
# This file is in https://github.com/wilsonmar/git-utilities/git-imerge-test-create.sh
