91/09/09 - JR - getmat.c:
                inserted space in nsteps=-1 (HP Unix compiler needs it)
93/01/14 - JR - fix_temp.c:
		modified to allow user to specify true_temperature, true_salinity,
		and offset_temperature as either a value or a file, in the case
		where a profile-by-profile correction is to be applied.  Note that
		the file must have time in decimal days as the first column and
		the temperature/offset/salinity value as the second column.  There
		should be a one-to-one correspondence between the file times and
		the ADCP database times within the user-specified time range--
		only a rounding error of 0.0001 is allowed between file and database
		times.  The control file now uses options, rather than parameters.
93/02/10 - EF - getmat.c:
		added code to work with LADCP data
93/07/28 - JR - fix_temp.c:
		moved n_vel initialization inside while loop so it will always
		get/rotate/put all bins (otherwise, switching from less to more bins
		can lead to a partially rotated profile)
95/06/21 - EF - getmat:
      Fixed bug in the checking of the command line,
      that could cause a segmentation fault.
96/10/02 - EF - 
   getmat:
      Added two command-line options: -r for raw amplitude
      output, and -t for specification of decimal-day time and
      interval instead of block-profile-nprofs.  getmatra is
      obsolete and has been deleted.
   setflags.c:
      New program to set and clear profile flags and
      access_variables first_good_bin and last_good_bin.
   set_lgb.c:
      New program that replaces botmpas3 and last85, which will
      soon be deleted.
   dbupdate.c:
      Modified to work in concert with set_lgb and setflags.
   fix_temp.c:
      Added null-termination line to option array.
   dbedit.c:
      Modified to work with set_lgb and setflags; in
      update_acc_var, acc.last_good_bin is updated unless it is
      -1 (bad profile); previously it was updated only if the
      update would reduce the value of last_good_bin.
