+.SH NAME
+puts \- Write to a channel
+.SH SYNOPSIS
+\fBputs \fR?\fB\-nonewline\fR? ?\fIchannelId\fR? \fIstring\fR
+.BE
+
+.SH DESCRIPTION
+.PP
+Writes the characters given by \fIstring\fR to the channel given
+by \fIchannelId\fR.
+\fIChannelId\fR must be a channel identifier such as returned from a
+previous invocation of \fBopen\fR or \fBsocket\fR. It must have been opened
+for output. If no \fIchannelId\fR is specified then it defaults to
+\fBstdout\fR. \fBPuts\fR normally outputs a newline character after
+\fIstring\fR, but this feature may be suppressed by specifying the
+\fB\-nonewline\fR switch.
+.PP
+Newline characters in the output are translated by \fBputs\fR to
+platform-specific end-of-line sequences according to the current
+value of the \fB\-translation\fR option for the channel (for example,
+on PCs newlines are normally replaced with carriage-return-linefeed
+sequences; on Macintoshes newlines are normally replaced with
+carriage-returns).
+See the \fBfconfigure\fR manual entry for a discussion of end-of-line
+translations.
+.PP
+Tcl buffers output internally, so characters written with \fBputs\fR
+may not appear immediately on the output file or device; Tcl will
+normally delay output until the buffer is full or the channel is
+closed.
+You can force output to appear immediately with the \fBflush\fR
+command.
+.PP
+When the output buffer fills up, the \fBputs\fR command will normally
+block until all the buffered data has been accepted for output by the
+operating system.
+If \fIchannelId\fR is in nonblocking mode then the \fBputs\fR command
+will not block even if the operating system cannot accept the data.
+Instead, Tcl continues to buffer the data and writes it in the
+background as fast as the underlying file or device can accept it.
+The application must use the Tcl event loop for nonblocking output
+to work; otherwise Tcl never finds out that the file or device is
+ready for more output data.
+It is possible for an arbitrarily large amount of data to be
+buffered for a channel in nonblocking mode, which could consume a
+large amount of memory.
+To avoid wasting memory, nonblocking I/O should normally
+be used in an event-driven fashion with the \fBfileevent\fR command
+(don't invoke \fBputs\fR unless you have recently been notified
+via a file event that the channel is ready for more output data).
