 A public-domain clone of the Korn shell called @command{pdksh} is widely
 available: it has most of the @samp{ksh88} features along with a few of
-its own.  Similarly to Bash, you can detect whether you are
-running @command{pdksh} by testing whether @code{KSH_VERSION} is set,
-and you can require Posix compatibility by running @samp{set
--o posix}.  Unfortunately, with @command{pdksh} 5.2.14 (the latest
-stable version as of January 2006) Posix mode is buggy and causes
-@command{pdksh} to depart from Posix in at least one respect:
