+.SH NAME
+\fBtabs\fR \- set tabs on a terminal
+.SH SYNOPSIS
+\fBtabs\fR [\fB\-v\fR[\fIn\fR]] [\fB\-ahuUV\fR] \fIfile...\fR
+.br
+.SH DESCRIPTION
+.PP
+The \fBtabs\fP program clears and sets tab-stops on the terminal.
+This uses the terminfo \fIclear_all_tabs\fP and \fIset_tab\fP capabilities.
+If either is absent, \fBtabs\fP is unable to clear/set tab-stops.
+The terminal should be configured to use hard tabs, e.g.,
+.sp
+.RS
+stty tab0
+.RE
+.SH OPTIONS
+.SS General Options
+.TP 5
+.BI \-T "name"
+Tell \fBtabs\fP which terminal type to use.
+If this option is not given, \fBtabs\fP will use the \fB$TERM\fP
+environment variable.
+If that is not set, it will use the \fIansi+tabs\fP entry.
+.TP 5
+.B \-d
+The debugging option shows a ruler line, followed by two data lines.
+The first data line shows the expected tab-stops marked with asterisks.
+The second data line shows the actual tab-stops, marked with asterisks.
+.TP 5
+.B \-n
+This option tells \fBtabs\fP to check the options and run any debugging
+option, but not to modify the terminal settings.
+.PP
+The \fBtabs\fP program processes a single list of tab stops.
+The last option to be processed which defines a list is the one that
+determines the list to be processed.
+.SS Implicit Lists
+Use a single number as an option, e.g., "\fB\-5\fP" to set tabs at the given
+interval (in this case 1, 6, 11, 16, 21, etc.). Tabs are repeated up to
+the right margin of the screen.
+.PP
+Use "\fB\-0\fP" to clear all tabs.
+.PP
+Use "\fB\-8\fP" to set tabs to the standard interval.
+.SS Explicit Lists
+An explicit list can be defined after the options (this does not use a "\-").
+The values in the list must be in increasing numeric order, and greater than
+zero. They are separated by a comma or a blank, for example,
+.sp
+.RS
+tabs 1,6,11,16,21
+.br
+tabs 1 6 11 16 21
+.RE
+Use a '+' to treat a number as an increment relative to the previous value,
+e.g.,
+.sp
+.RS
+tabs 1,+5,+5,+5,+5
+.RE
+which is equivalent to the 1,6,11,16,21 example.
+.SS Predefined Tab-Stops
+X/Open defines several predefined lists of tab stops.

+.SH PORTABILITY
+.PP
+X/Open describes a \fB+m\fP option, to set a terminal's left-margin.
+Very few of the entries in the terminal database provide this capability.
+.PP
+The \fB\-d\fP (debug) and \fB\-n\fP (no-op) options are extensions not provided
+by other implementations.
+.PP
+Documentation for other implementations states that there is a limit on the
+number of tab stops. While some terminals may not accept an arbitrary number
+of tab stops, this implementation will attempt to set tab stops up to the
+right margin of the screen, if the given list happens to be that long.
