  .Pp
  Message levels have the following meanings:
  .Bl -tag -width "warning"
! .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.
  .Pp
  Non-existent or unreadable input files are also reported on the
  .Cm error

  .Pp
  Message levels have the following meanings:
  .Bl -tag -width "warning"
! .It Cm unsupp
! An input file uses unsupported low-level
! .Xr roff 7
! features.
! The output may be incomplete and/or misformatted,
! so using GNU troff instead of
  .Nm
! to process the file may be preferable.
! .It Cm error
! An input file contains invalid syntax that cannot be safely interpreted.
  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, no matter whether
! .Nm
! or GNU troff is used.
! In many cases, the output of
! .Nm
! and GNU troff is identical, but in some,
! .Nm
! is more resilient than GNU troff with respect to malformed input.

  Non-existent or unreadable input files are also reported on the
