#
# Create a Pull Request
#
# In order to create a Pull Request from the current branch we need to
# know the base branch of the Pull Request (also known as the "target"
# of the Pull Request). If the current branch name contains a configured
# base branch as substring, then this is used. If no base branch was
# found, then the default base branch is used if configured. Afterwards
# the script creates a Pull Request on GitHub.
#
# After the initial repository clone, change directory to your Git
# repository and setup...
#
# ... your default base branch:
# $ git config --local adsk.pr-base-default "<BRANCH-NAME>"
#
# ... your base branches:
# $ git config --local adsk.pr-base-branch-<BRANCH-NAME> "<BRANCH-NAME>"
#
#
# Example:
# $ git config --local adsk.pr-base-default "master"
# $ git config --local adsk.pr-base-branch-releasev3 "releasev3"
#
#
# Usage: git <KIT_ID> mkpr
#
