+.SH NAME
+lam \- laminate files
+.SH SYNOPSIS
+.B lam [ \-[fp]
+min.max
+.B ] [ \-s
+sepstring
+.B ] [ \-t
+c
+.B ]
+file ...
+.SH DESCRIPTION
+.I Lam
+copies the named files side by side onto the standard output.
+The
+.IR n -th
+input lines from the input
+.IR file s
+are considered fragments of the single long
+.IR 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
+.I file
+after it.
+If the option letter is capitalized it affects all subsequent files
+until it appears again uncapitalized.
+The options are described below.
+.IP \fB\-f\fP\ min.max
+Print line fragments according to the format string
+.IR min.max ,
+where
+.I min
+is the minimum field width and
+.I max
+the maximum field width.
+If
+.I 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.
+.IP \fB\-p\fP\ min.max
+Like \fB\-f\fP,
+but pad this file's field when end-of-file is reached
+and other files are still active.
+.IP \fB\-s\fP\ sepstring
+Print
+.I sepstring
+before printing line fragments from the next file.
+This option may appear after the last file.
+.IP \fB\-t\fP\ c
+The input line terminator is
+.I c
+instead of a newline.
+The newline normally appended to each output line is omitted.
+.PP
+To print files simultaneously for easy viewing use
+.IR pr (1).
+.SH EXAMPLES
+.de IC
+.IP
+.ss 36
+.ft B
+..
+.de NC
+.br
+.ss 12
+.PP
+..
+.PP
+The command
+.IC
+lam file1 file2 file3 file4
+.NC
+joins 4 files together along each line.
+To merge the lines from four different files use
+.IC
+lam file1 \-S "\\
+.br
+" file2 file3 file4
+.NC
+Every 2 lines of a file may be joined on one line with
+.IC
+lam \- \- < file
+.NC
+and a form letter with substitutions keyed by `@' can be done with
+.IC
+lam \-t @ letter changes
+.NC
+.SH SEE ALSO
+join(1), pr(1), printf(3)
