-# miscellaneous Workhorse-specific utilities
-
-# History:
-#	Feb 12, 2003: - created
-#	Feb 14, 2003: - added check for short (bad) data files
-#	Feb 26, 2004: - added Earth-coordinate support
-#				  - added ensure_BT_RANGE()
-#	Mar 17, 2004: - set bad BT ranges to undef in ensure_BT_RANGE
-#				  - calc mean/stddev in ensure_BT_RANGE
-#	Mar 20, 2004: - BUG: find_seabed() could bomb when not enough
-#					bottom guesses passed the mode_width test
-#	Mar 30, 2004: - added &soundSpeed()
-#	Nov  8, 2005: - WATER_DEPTH => Z_BT
-#	May 23, 2010: - Z* -> DEPTH*
