=head1 EXPORTED SYMBOLS
-By default your system's F_* and O_* constants (eg, F_DUPFD and O_CREAT)
-are exported into your namespace. You can request that the flock()
-constants (LOCK_SH, LOCK_EX, LOCK_NB and LOCK_UN) be provided by using
-the tag C<:flock>. See L<Exporter>.
+By default your system's F_* and O_* constants (eg, F_DUPFD and
+O_CREAT) and the FD_CLOEXEC constant are exported into your namespace.
+
+You can request that the flock() constants (LOCK_SH, LOCK_EX, LOCK_NB
+and LOCK_UN) be provided by using the tag C<:flock>. See L<Exporter>.
+
+You can request that the old constants (FAPPEND, FASYNC, FCREAT,
+FDEFER, FEXCL, FNDELAY, FNONBLOCK, FSYNC, FTRUNC) be provided for
+compatibility reasons by using the tag C<:Fcompat>. For new
+applications the newer versions of these constants are suggested
+(O_APPEND, O_ASYNC, O_CREAT, O_DEFER, O_EXCL, O_NDELAY, O_NONBLOCK,
+O_SYNC, O_TRUNC).
+
+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.
+
+See L<perlfunc/stat> about the S_I* constants.
