+# The idea behind this Action is to prevent the situation where a user
+# files a Github Issue, someone asks for clarification / more
+# information, but the original poster never provides the information.
+# The issue then becomes forgotten and abondoned.
+#
+# Instead of that scenario, PMIx community members can assign a
+# label to Github Issues indicating that we're waiting for the user to
+# reply.  If too much time elapses with no reply, mark the Issue as
+# stale and emit a warning that we'll close the issue if we continue
+# to receive no reply.  If we timeout again with no reply after the
+# warning, close the Issue and emit a comment explaining why.
+#
+# If the user *does* reply, the label is removed, and this bot won't
+# touch the Issue.  Specifically: this bot will never mark stale /
+# close an Issue that doesn't have the specified label.
+#
+# Additionally, we are *only* marking stale / auto-closing Github
+# Issues -- not Pull Requests.
+#
+# This is a cron-based Action that runs a few times a day, just so
+# that we don't mark stale / close a bunch of issues all at once.
+#
+# While the actions/stale bot Action used here is capable of removing
+# the label when a user replies to the Issue, we actually use a 2nd
+# Action (removing-awaiting-user-info-label.yaml) to remove the label.
+# We do this because that 2nd Action runs whenever a comment is
+# created -- not via cron.  Hence, the 2nd Action will remove the
+# label effectively immediately when the user replies (vs. up to
+# several hours later).
