version prints out the version of Solaris that a command first appeared in,

        $ version perl
	perl        Solaris 8        2000


It's a handy program for those of us who work on multiple versions of
Solaris, as a reminder of which versions can do what.

        $ version coreadm dumpadm adb mdb
	coreadm     Solaris 8        2000  
	dumpadm     Solaris 7        1998  
	adb         Solaris <2.5     <1994 
	mdb         Solaris 8        2000 


... or when we encounter new commands,

        $ version pkgadm
	pkgadm      Solaris 9 12/03  2003
