+If a called routine fails with an error, the \fBbgerror\fR routine for the interpreter is invoked after command completion.
+Only exception is the callback \fBunknowncmd\fR, where an error causes the invoking \fBmc\fR-command to fail with that error.
+.PP
+.SS Examples
+Packages which display a GUI may update their widgets when the global locale changes.
+To register to a callback, use:
+.CS
+namespace eval gui {

+
+    proc updateGui args {
+        puts "New locale is '[lindex $args 0]'."
+    }
+}
+% msgcat::mclocale fr
+fr
+% New locale is 'fr'.
+.CE
+.PP
+If locales (or additional locales) are contained in another source like a data base, a package may use the load callback and not mcload:
+.CS
+namespace eval db {
+    msgcat::mcpackageconfig loadcmd loadMessages
+
+    proc loadMessages args {
+        foreach locale $args {

+.PP
+The \fBclock\fR command implementation uses \fBmsgcat\fR with a package locale to implement the command line parameter \fB-locale\fR.
+Here are some sketches of the implementation:
+.PP
+First, a package locale is initialized and the generic unknown function is desactivated:
+.CS
+msgcat::mcpackagelocale set
+msgcat::mcpackageconfig unknowncmd ""
+.CE
+As an example, the user requires the week day in a certain locale as follows:
+.CS
+clock format clock seconds -format %A -locale fr
+.CE
+\fBclock\fR sets the package locale to \fBfr\fR and looks for the day name as follows:
+.CS
+msgcat::mcpackagelocale set $locale
+return [lindex [msgcat::mc DAYS_OF_WEEK_FULL] $day]
+### Returns "mercredi"
+.CE
+Within \fBclock\fR, some message-catalog items are heavy in computation and thus are dynamically cached using:
+.CS
+proc ::tcl::clock::LocalizeFormat { locale format } {
+    set key FORMAT_$format
+    if { [::msgcat::mcexists -exactlocale -exactnamespace $key] } {
+        return [mc $key]
+    }
+    #...expensive computation of format clipped...
+    mcset $locale $key $format
+    return $format
