+File::Spec::VMS - methods for VMS file specs
+
+=head1 SYNOPSIS
+
+ require File::Spec::VMS; # Done internally by File::Spec if needed
+
+=head1 DESCRIPTION
+
+See File::Spec::Unix for a documentation of the methods provided
+there. This package overrides the implementation of these methods, not
+the semantics.
+
+The default behavior is to allow either VMS or Unix syntax on input and to
+return VMS syntax on output unless Unix syntax has been explicitly requested
+via the C<DECC$FILENAME_UNIX_REPORT> CRTL feature.
