-what constants are implemented in your system.
+For ease of use also the SEEK_* constants (for seek() and sysseek(),
+e.g. SEEK_END) and the S_I* constants (for chmod() and stat()) are
+available for import.  They can be imported either separately or using
+the tags C<:seek> and C<:mode>.

+Please refer to your native fcntl(2), open(2), fseek(3), lseek(2)
+(equal to Perl's seek() and sysseek(), respectively), and chmod(2)
+documentation to see what constants are implemented in your system.
+
+See L<perlopentut> to learn about the uses of the O_* constants
+with sysopen().

+See L<perlfunc/seek> and L<perlfunc/sysseek> about the SEEK_* constants.
