   9 // file", which is an HCL config file whose top-level attributes are treated
  10 // as arbitrary key.value pairs.

  12 // If the file cannot be read -- for example, if it does not exist -- then
  13 // a nil map will be returned along with error diagnostics. Callers may wish
  14 // to disregard the returned diagnostics in this case and instead generate
  15 // their own error message(s) with additional context.

  18 // then the map may be incomplete but should be valid enough for careful
  19 // static analysis.

  22 // behaviors documented for that method.
