  20     # Checks the MD5 sum of the given file. Will return failure if the MD5 sum
  21     # is incorrect, the file is missing, or the MD5 sum file is missing.
  22     #
  23     # The MD5 sum must be stored in a separate file with the same name as the
  24     # file to be tested, with ".md5" appended. Eg., if the file is "foo.txt",
  25     # then the MD5 sum must be stored in "foo.txt.md5". The format of the file
  26     # is that of the output from the GNU md5sum command.
  27     #
  28     # Inputs:
  29     # $1 - path of file to check.
  30     #
  31     # Outputs:
  32     # $? - 0 if file is OK, !0 if FAILED.
