+--  This is a small utility program that incorporates the file krunching
+--  algorithm used by the GNAT compiler (when the -gnatk switch is used)
+
+--     gnatkr  filename  length
+
+--  where length is a decimal value, outputs to standard output the krunched
+--  name, followed by the original input file name. The file name has an
+--  optional extension, which, if present, is copied unchanged to the output.
+--  The length argument is optional and defaults to the system default if
+--  there is one, otherwise to 8.
+
+procedure Gnatkr;
+--  Execute above described command. This is an Ada main program which
+--  sets an exit status (set to Success or Failure as appropriate)
