+.Sh NAME
+.Nm vgaio
+.Nd perform input/output on a Video Graphics Array
+.Sh SYNOPSIS
+.Nm vgaio
+.Op Fl d
+.Sh DESCRIPTION
+.Ss Purpose
+.Nm Vgaio
+is used to perform register-level input/output on a Video Graphics Array.
+Since some of the sequences required to access those registers are very
+silly,
+.Nm vgaio
+cares of all the things necessary and allows the user to access the
+registers of several register groups with their symbolic names.
+
+.Ss Options
+.Bl -tag -width 10n -offset indent
+.It Fl d
+Turn on the grammar parser debugger.
+
+.El
+.Ss Command language
+The command language of
+.Nm
+constitutes of some very simple tokens and rules. Commands are executed
+line by line as they are entered. Each line may contain any number of
+semicolon-separated input/output commands.
+
+Symbolic register names look like:
+
+.D1 Ao Em reggroup Ac Ao Em regnumber Ac
+
+with
+.Aq Em regnumber
+being any hexadecimal number
+.Pq without a leading Em 0x ,
+and
+.Aq Em reggroup
+one of the strings
+.Dq Em ar ,
+.Dq Em cr ,
+.Dq Em gr ,
+.Dq Em mi ,
+or
+.Dq Em sr ,
+standing for the
+.Em Attribute controller ,
+.Em CRT controller ,
+.Em Graphics controller ,
+.Em Miscellaneous Output Register ,
+or
+.Em Timing sequencer ,
+respectively.
+
+An input instruction has the form
+
+.D1 Ao Em regname Ac ?
+
+and will cause
+.Nm
+to output a line like
+
+.Bd -ragged -offset indent
+.Ao Em regname Ac \& = 0x Ns
+.Aq Em number
+.Ed
+
+An output instruction looks like
+
+.Bd -ragged -offset indent
+.Ao Em regname Ac =
+.Aq Em number
+.Ed
+
+Spaces or Tabs between the
+.Aq Em reggroup ,
+the
+.Aq Em regnumber ,
+or any of the other tokens are ignored. They are not required anyway.
+
+The 
+.Dq Em mi
+needs a single unused argument to satisfy the syntax :-) (-hm).
+
+
+.Ss Access control
+The caller must have uid 0 in order to gain the required access to
+the IO registers.
+
+.Sh HISTORY
+This program is considered
+.Dq hackware .
+It has been developed in order to simplify the process of developing other
+software that needs to program the Video Graphics Array.
+
+Remember, to use this program, your kernel has to be compiled with XSERVER
+being defined !
+
+.Sh AUTHOR
+The program has been contributed by
+.if n Joerg Wunsch,
+.if t J\(:org Wunsch,
+Dresden
+.Aq joerg_wunsch@uriah.sax.de .
