=head1 NAME

File::stat - by-name interface to Perl's built-in stat() functions

=head1 SYNOPSIS

 use File::stat;
 $st = stat($file) or die "No $file: $!";
 if ( ($st->mode & 0111) && $st->nlink > 1) ) {
     print "$file is executable with lotsa links\n";
 } 

 use File::stat qw(:FIELDS);
 stat($file) or die "No $file: $!";
 if ( ($st_mode & 0111) && ($st_nlink > 1) ) {
     print "$file is executable with lotsa links\n";
 } 

=head1 DESCRIPTION

This module's default exports override the core stat() 
and lstat() functions, replacing them with versions that return 
"File::stat" objects.  This object has methods that
return the similarly named structure field name from the
stat(2) function; namely,
dev,
ino,
mode,
nlink,
uid,
gid,
rdev,
size,
atime,
mtime,
ctime,
blksize,
and
blocks.  

You may also import all the structure fields directly into your namespace
as regular variables using the :FIELDS import tag.  (Note that this still
overrides your stat() and lstat() functions.)  Access these fields as
variables named with a preceding C<st_> in front their method names.
Thus, C<$stat_obj-E<gt>dev()> corresponds to $st_dev if you import
the fields.

To access this functionality without the core overrides,
pass the C<use> an empty import list, and then access
function functions with their full qualified names.
On the other hand, the built-ins are still available
via the C<CORE::> pseudo-package.

=head1 BUGS

As of Perl 5.8.0 after using this module you cannot use the implicit
C<$_> or the special filehandle C<_> with stat() or lstat(), trying
to do so leads into strange errors.  The workaround is for C<$_> to
be explicit

    my $stat_obj = stat $_;

and for C<_> to explicitly populate the object using the unexported
and undocumented populate() function with CORE::stat():

    my $stat_obj = File::stat::populate(CORE::stat(_));

=head1 NOTE

While this class is currently implemented using the Class::Struct
module to build a struct-like class, you shouldn't rely upon this.
