+=head1 NAME
+
+Fcntl - load the C Fcntl.h defines
+
+=head1 SYNOPSIS
+
+    use Fcntl;
+    use Fcntl qw(:DEFAULT :flock);
+
+=head1 DESCRIPTION
+
+This module is just a translation of the C F<fnctl.h> file.
+Unlike the old mechanism of requiring a translated F<fnctl.ph>
+file, this uses the B<h2xs> program (see the Perl source distribution)
+and your native C compiler.  This means that it has a 
+far more likely chance of getting the numbers right.
+
+=head1 NOTE
+
+Only C<#define> symbols get translated; you must still correctly
+pack up your own arguments to pass as args for locking functions, etc.
+
+=head1 EXPORTED SYMBOLS
+
+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).
+
+Please refer to your native fcntl() and open() documentation to see
+what constants are implemented in your system.
