+.\" SECTION
+.Sh COMPATIBILITY
+This section documents compatibility with other roff implementations, at
+this time limited to
+.Xr groff 1 .
+The term
+.Qq historic groff
+refers to those versions before the
+.Pa doc.tmac
+file re-write
+.Pq somewhere between 1.15 and 1.19 .
+.Pp
+.Bl -dash -compact
+.\" LIST-ITEM
+.It
+Some character sequences in groff are not handled depending on escape
+style, e.g.,
+.Sq \e(ba
+and
+.Sq \e*(Ba
+may not be interchanged. This is no longer the case: all character
+sequences resolve to the same symbol, regardless the escape style.
+.\" LIST-ITEM
+.It
+Blocks of whitespace are stripped from both macro and free-form text
+lines (except when in literal mode), while groff would retain whitespace
+in free-form text lines.
+.\" LIST-ITEM
+.It
+Historic groff has many un-callable macros. Most of these (excluding
+some block-level macros) are now callable, conforming to the
+non-historic groff version.
+.\" LIST-ITEM
+.It
+The vertical bar
+.Sq \(ba
+made historic groff
+.Qq go orbital
+but is a proper delimiter in this implementation.
+.\" LIST-ITEM
+.It
+.Sq \&.It \-nested
+is assumed for all lists (it wasn't in historic groff): any list may be
+nested and
+.Sq \-enum
+lists will restart the sequence only for the sub-list.
+.\" LIST-ITEM
+.It
+.Sq \&.It \-column
+syntax where column widths may be preceded by other arguments (instead
+of proceeded) is not supported.
+.\" LIST-ITEM
+.It
+The
+.Sq \&.At
+macro only accepts a single parameter.
+.\" LIST-ITEM
+.It
+Some manuals use
+.Sq \&.Li
+incorrectly by following it with a reserved character and expecting the
+delimiter to render. This is not supported.
+.\" LIST-ITEM
+.It
+If an special-character control character is escaped
+.Sq \e\e ,
+it will obviously not render the subsequent sequence. Even newer
+versions of groff seem to dither on this.
+.\" LIST-ITEM
+.It
+In groff, the
+.Sq \&.Fo
+macro only produces the first parameter. This is no longer the case.
