-.SH NAME
-update \- Process pending events and idle callbacks
-.SH SYNOPSIS
-\fBupdate\fR ?\fBidletasks\fR?
-.BE
-
-.SH DESCRIPTION
-.PP
-This command is used to bring the application ``up to date''
-by entering the event loop repeated until all pending events
-(including idle callbacks) have been processed.
-.PP
-If the \fBidletasks\fR keyword is specified as an argument to the
-command, then no new events or errors are processed; only idle
-callbacks are invoked.
-This causes operations that are normally deferred, such as display
-updates and window layout calculations, to be performed immediately.
-.PP
-The \fBupdate idletasks\fR command is useful in scripts where
-changes have been made to the application's state and you want those
-changes to appear on the display immediately, rather than waiting
-for the script to complete. Most display updates are performed as
-idle callbacks, so \fBupdate idletasks\fR will cause them to run.
-However, there are some kinds of updates that only happen in
-response to events, such as those triggered by window size changes;
-these updates will not occur in \fBupdate idletasks\fR.
-.PP
-The \fBupdate\fR command with no options is useful in scripts where
-you are performing a long-running computation but you still want
-the application to respond to events such as user interactions; if
-you occasionally call \fBupdate\fR then user input will be processed
-during the next call to \fBupdate\fR.
