-    The \\expire command allows you to define an expiration
-    date for your documentation.
-
-    When using the \\expire command, QDoc will emit a warning when the
-    current date is larger than the specified date. The command
-    accepts one argument; the argument's format is yyyy-mm-dd. For
-    example:
-
-           \code
-           / *!
-               \page porting.html
-
-               \title Porting to Qt 3.x
