45 * This program un-does what "strfile" makes, thereby obtaining the
46 * original file again. This can be invoked with the name of the output
47 * file, the input file, or both. If invoked with only a single argument
48 * ending in ".dat", it is pressumed to be the input file and the output
49 * file will be the same stripped of the ".dat". If the single argument
50 * doesn't end in ".dat", then it is presumed to be the output file, and
51 * the input file is that name prepended by a ".dat". If both are given
52 * they are treated literally as the input and output files.
