+# Set the name of the end-user facing command in the reflog when the

+# another scripted Porcelain (e.g. "git am") and a call to this

+# program (e.g. "rebase") in GIT_REFLOG_ACTION, ensuring whatever it
+# does will be record as actions done as part of the end-user facing
+# operation (e.g. "rebase").
+#
+# NOTE NOTE NOTE: consequently, after assigning a specific message to
+# GIT_REFLOG_ACTION when calling a "git" command to record a custom
+# reflog message, do not leave that custom value in GIT_REFLOG_ACTION,
+# after you are done. Other callers of "git" commands that rely on
+# writing the default "program name" in reflog expect the variable to
+# contain the value set by this function.
+#
+# To use a custom reflog message, do either one of these three:
+#
+# (a) use a single-shot export form:
+# GIT_REFLOG_ACTION="$GIT_REFLOG_ACTION: preparing frotz" \
+# git command-that-updates-a-ref

+# GIT_REFLOG_ACTION="$GIT_REFLOG_ACTION: preparing frotz"
+# git command-that-updates-a-ref
+# GIT_REFLOG_ACITON=$SAVED_ACTION
