+# nut-recorder
+#   An utility to record device running sequence (Ie power failures or any
+#   other change) and dump it in a .seq format
+#   The .seq file can then be used by the 'dummy-ups driver to replay the
+#   sequence.
+#
+################################################################################
+# FIXME:
+#  - implement PAUSE / RESUME (do not increment TIMER) on pressing space (?)
+#  - implement support for creating either .dev (static dump) or .seq
+#  - implement dump of instcmd and upsrw
