+@cmd{INSERT} is similar to @cmd{INCLUDE} (@pxref{INCLUDE})
+but somewhat more flexible.
+It causes the command processor to read a file as if it were embedded in the
+current command file.
+
+If @samp{CD=YES} is specified, then before including the file, the
+current directory will be changed to the directory of the included
+file.
+The default setting is @samp{CD=NO}.
+Note that this directory will remain current until it is
+changed explicitly (with the @cmd{CD} command, or a subsequent
+@cmd{INSERT} command with the @samp{CD=YES} option).
+It will not revert to its original setting even after the included
+file is finished processing.
+
+If @samp{ERROR=STOP} is specified, errors encountered in the
+inserted file will cause processing to immediately cease.
+Otherwise processing will continue at the next command.
+The default setting is @samp{ERROR=CONTINUE}.
+
+If @samp{SYNTAX=INTERACTIVE} is specified then the syntax contained in
+the included file must conform to interactive syntax
+conventions. @xref{Syntax Variants}.
+The default setting is @samp{SYNTAX=BATCH}.
