+
+# HISTORY:
+#	Aug 25, 2006: - created from [listEns]
+#	Aug 26, 2006: - added -M)agdecl
+#				  - changed -b to -f
+#	Aug 27, 2006: - added %bin
+#	Aug 28, 2006: - BUG: options were confused
+#	Jan  4, 2007: - improved usage message for -a
+#				  - added %mag_decl
+#				  - BUG: roundoff error in %pct_good_vels
+#	Sep 19, 2007: - adapted to new [RDI_BB_Read.pl]
+#	Feb  7, 2008: - added sound-speed correction
+#				  - enabled 3-beam solutions
+#	Feb  8, 2008: - added -d)iscard <beam>
+#				  - added -b)eam coordinate output
+#	Feb 12, 2008: - modified 3-beam output
+#				  - added -p)ct_good <min>
+#	Feb 13, 2008: - various improvements
+#	Feb 19, 2008: - BUG: division by zero
+#					BUG: min() did not work with 1st elt undef
+#	Feb 21, 2008: - BUG: had forgotten to undo debugging changes
+#				  - removed missing magdecl warning on -b
+#	Feb 22, 2008: - moved ssCorr() to [RDI_Utils.pl]
+#				  - BUG: %d complete ensembles was written to STDOUT
+#				  - BUG: %N_ensembles was total number of ensembles, not
+#						 only the ones used
+#				  - BUG: 0 errvel was output for 3-beam solutions =>
+#						 wrong time-average statistics
+#	May 19, 2009: - added -w to calculate vertical velocities from
+#					two beam pairs separately
+#	May 21, 2009: - added horizontal beampair velocities on -w
+#				  - -P)itchRoll <bias/bias>
+#	May 22, 2009: - added -B) <bias/bias/bias/bias>
+#	May 23, 2009: - adapted to changed beampair-velocity fun name
+
+# General Notes:
+#	- everything (e.g. beams) is numbered from 1
+#	- no support for BT data
+
+# Soundspeed Correction:
+#	- applied as described in the RDI coord-trans manual
+#	- sound-speed variation over range is ignored (valid for small gradients)
+#	=> - same simple correction for all velocity components
+#	   - simple correction for cell depths
+
+# Min %-good (min_pcg):
+#	- nan for records w/o valid velocities
+#	- min(%-good) of the beams used for the velocity solution
+#	- min_pcg does not have to decrease monotonically with distance,
+#	  at least when 3-beam solutions are allowed and when -p is used to
+#	  edit the data
+#	- non-monotonic min_pcg is particularly obvious with the DYNAMUCK BM_ADCP
+#	  data, where one of the beams performed much worse than the others
