+(defun insert-file-contents (filename &optional visit beg end replace)

+Returns list of absolute file name and length of data inserted.
+If second argument VISIT is non-nil, the buffer's visited filename
+and last save file modtime are set, and it is marked unmodified.
+If visiting and the file does not exist, visiting is completed
+before the error is signaled.
+
+The optional third and fourth arguments BEG and END
+specify what portion of the file to insert.
+If VISIT is non-nil, BEG and END must be nil.
+If optional fifth argument REPLACE is non-nil,
+it means replace the current buffer contents (in the accessible portion)
+with the file contents.  This is better than simply deleting and inserting
+the whole thing because (1) it preserves some marker positions
+and (2) it puts less data in the undo list."

+When called from a program, takes three arguments:
+START, END and FILENAME.  START and END are buffer positions.
+Optional fourth argument APPEND if non-nil means
+  append to existing file contents (if any).
+Optional fifth argument VISIT if t means
+  set the last-save-file-modtime of buffer to this file's modtime
+  and mark buffer not modified.
+If VISIT is a string, it is a second file name;
+  the output goes to FILENAME, but the buffer is marked as visiting VISIT.
+  VISIT is also the file name to lock and unlock for clash detection.
+If VISIT is neither t nor nil nor a string,
+  that means do not print the \"Wrote file\" message.
+The optional sixth arg LOCKNAME, if non-nil, specifies the name to
+  use for locking and unlocking, overriding FILENAME and VISIT.
