+.Sh NAME
+.Nm lam
+.Nd laminate files
+.Sh SYNOPSIS
+.Nm
+.Op Fl f Ar min . Ns Ar max
+.Op Fl s Ar sepstring
+.Op Fl t Ar c
+.Ar
+.Nm
+.Op Fl p Ar min . Ns Ar max
+.Op Fl s Ar sepstring
+.Op Fl t Ar c
+.Ar
+.Sh DESCRIPTION
+The
+.Nm
+utility copies the named files side by side onto the standard output.
+The
+.Em n-th
+input lines from the input
+.Ar files
+are considered fragments of the single long
+.Em n-th
+output line into which they are assembled.
+The name `\fB\-\fP' means the standard input, and may be repeated.
+.Pp
+Normally, each option affects only the
+.Ar file
+after it.
+If the option letter is capitalized it affects all subsequent files
+until it appears again uncapitalized.
+The options are described below:
+.Bl -tag -width indent
+.It Fl f Ar min . Ns Ar max
+Print line fragments according to the format string
+.Ar min . Ns Ar max ,
+where
+.Ar min
+is the minimum field width and
+.Ar max
+the maximum field width.
+If
+.Ar min
+begins with a zero, zeros will be added to make up the field width,
+and if it begins with a `\-', the fragment will be left-adjusted
+within the field.
+.It Fl p Ar min . Ns Ar max
+Like
+.Fl f ,
+but pad this file's field when end-of-file is reached
+and other files are still active.
+.It Fl s Ar sepstring
+Print
+.Ar sepstring
+before printing line fragments from the next file.
+This option may appear after the last file.
+.It Fl t Ar c
+The input line terminator is
+.Ar c
+instead of a newline.
+The newline normally appended to each output line is omitted.
+.El
+.Pp
+To print files simultaneously for easy viewing use
+.Xr pr 1 .
+.Sh EXAMPLES
+The command
+.Bd -literal
+lam file1 file2 file3 file4
+.Ed
+.Pp
+joins 4 files together along each line.
+To merge the lines from four different files use
+.Bd -literal
+lam file1 \-S "\\
+" file2 file3 file4
+.Ed
+.Pp
+Every 2 lines of a file may be joined on one line with
+.Bd -literal
+lam \- \- < file
+.Ed
+.Pp
+and a form letter with substitutions keyed by `@' can be done with
+.Bd -literal
+lam \-t @ letter changes
+.Ed
+.Sh SEE ALSO
+.Xr join 1 ,
+.Xr paste 1 ,
+.Xr pr 1 ,
+.Xr printf 3
+.Sh STANDARDS
+Some of the functionality of
+.Nm
+is standardized as the
+.Xr paste 1
+utility by
+.St -p1003.2 .
+.Sh BUGS
+The
+.Nm
+utility does not recognize multibyte characters.
