+This is a port of Perl version 5, revision 7, to VOS.  Perl
 is a scripting or macro language that is popular on many
 systems.  See your local computer bookstore for a number of good
 books on Perl.

+support on VOS.  There is an alpha version of POSIX that is
+available from the Stratus anonymous ftp site
+(ftp://ftp.stratus.com/pub/vos/posix/alpha/alpha.html).  There
+is a generally-available version of POSIX that comes with the
+VOS Standard C compiler and C runtime in VOS Release 14.3.0 or
+higher.  This port of POSIX will compile and bind with either
+version of POSIX.
+
+Most of the Perl features should work on VOS regardless of which
+version of POSIX that you are using.  However, the alpha version
+of POSIX is missing a number of key functions, and therefore any
 attempt by perl.pm to call the following unimplemented POSIX
 functions will result in an error message and an immediate and
 fatal call to the VOS debugger.  They are "dup", "fork", and
 "waitpid".  The lack of these functions pretty much prevents you
 from starting VOS commands and grabbing their output in perl.
 The workaround is to run the commands outside of perl, then have
-perl process the output file.
+perl process the output file.  These functions are all available
+in the generally-available version of POSIX.
