# This script displays the last 25 "issue branches" in order of last commit.
# An issue branch is a Git branch in the following format: bugfix/CMS2-123-fix-something,
# task/CMS2-234-new-feature, hotfix/CMS2-345-fix-crash, etc.
#
# These branches are displayed in a nice format with link to the Jira issue.
# Non issue branches (develop, master, etc.) are not displayed.
#
# Each issue branch line has the following format:
#

#          task CMS2-745 overpayments   Implement overpayments CSV API                   Michiel Sikma  3 months ago
