    2626! -----------------
    2727! $Id$
    28 ! Removed unnecessary check for output file
     28! Added command-line options for configuring the computation of geostrophic
     29!     winds (--averagin-mode, --averaging-angle)
     30! Added command-line option --input-prefix for setting input file prefixes all
     31!     at once
     32! Added --debug option for more verbose terminal output
     33! Added option-specific *_is_set LOGICALs to indicate invocation from the
     34!     command-line
     35! Improved error messages in case of empty file-name strings
     36! Improved routine naming
    2937!
