   .It Ar level

   .Pp
   Message levels have the following meanings:
   .Bl -tag -width "warning"
   .It Cm fatal
   The parser is unable to parse a given input file at all.
   No formatted output is produced from that input file.
   .It Cm error
   An input file contains syntax that cannot be safely interpreted,
   either because it is invalid or because
   .Nm
   does not implement it yet.
   By discarding part of the input or inserting missing tokens,
   the parser is able to continue, and the error does not prevent
   generation of formatted output, but typically, preparing that
   output involves information loss, broken document structure
   or unintended formatting.
   .It Cm warning
   An input file uses obsolete, discouraged or non-portable syntax.
   All the same, the meaning of the input is unambiguous and a correct
   rendering can be produced.
   Documents causing warnings may render poorly when using other
   formatting tools instead of
   .Nm .
