+# Usage: test_commit_bulk [options] <nr>
+# -C <dir>:
+# Run all git commands in directory <dir>
+# --ref=<n>:
+# ref on which to create commits (default: HEAD)
+# --start=<n>:
+# number commit messages from <n> (default: 1)
+# --message=<msg>:
+# use <msg> as the commit mesasge (default: "commit %s")
+# --filename=<fn>:
+# modify <fn> in each commit (default: %s.t)
+# --contents=<string>:
+# place <string> in each file (default: "content %s")
+# --id=<string>:
+# shorthand to use <string> and %s in message, filename, and contents
+#
+# The message, filename, and contents strings are evaluated by printf, with the
+# first "%s" replaced by the current commit number. So you can do:
+#
+# test_commit_bulk --filename=file --contents="modification %s"
+#
+# to have every commit touch the same file, but with unique content.
