+.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 .
