-.SH NAME
-exit \- End the application
-.SH SYNOPSIS
-\fBexit \fR?\fIreturnCode\fR?
-.BE
-
-.SH DESCRIPTION
-.PP
-Terminate the process, returning \fIreturnCode\fR to the
-system as the exit status.
-If \fIreturnCode\fR is not specified then it defaults
-to 0.
-.SH EXAMPLE
-.PP
-Since non-zero exit codes are usually interpreted as error cases by
-the calling process, the \fBexit\fR command is an important part of
-signaling that something fatal has gone wrong. This code fragment is
-useful in scripts to act as a general problem trap:
-.PP
-.CS
-proc main {} {
- # ... put the real main code in here ...
-}
-
-if {[catch {main} msg options]} {
- puts stderr "unexpected script error: $msg"
- if {[info exists env(DEBUG)]} {
- puts stderr "---- BEGIN TRACE ----"
- puts stderr [dict get $options -errorinfo]
- puts stderr "---- END TRACE ----"
- }
-
- # Reserve code 1 for "expected" error exits...
- \fBexit\fR 2
