+# Purpose
+# The purpose of this script is to facilitate auto-tagging of
+# Jira tickets with fix-versions. There are two tricky parts to auto-tagging:
+#
+# 1. Given a change set (PR diff), what constitutes a change to a service?
+# 2. Given you've determined a set of files has changed a service, which service was changed?
+#
+# This script endeavors to answer question number one - which files constitute a change to a service
+# Given an input file which is the git diff from a PR
+# this script should determine what file changes in the diff
+# constitute a material change to a service. At the time
+# of this writing, this currently only identifies java and go
+# files, and if those files are in the change list, then those
+# file names are returned in the output file.
+#
+# Inputs
+# $1 - File containing unique changed files
+# $2 - the output file which should ultimately contain file names from the diff that affect a service
+#
+# See BT-10437 for more information
+#
+# Called by https://harness0.harness.io/ng/account/l7B_kbSEQD2wjrM7PShm5w/all/orgs/Audit/projects/Engops_Audit/pipelines/PRMergedGithub/pipeline-studio/?storeType=INLINE
+# Unlike other scripts for detecting changes, this one doesn't receive a git diff, rather a unique list of files changed by the git update.
