NAME
    "File::lchown" - modify attributes of symlinks without dereferencing
    them

SYNOPSIS
     use File::lchown qw( lchown lutimes );

     lchown $uid, $gid, $linkpath or die "Cannot lchown() - $!";

     lutimes $atime, $mtime, $linkpath or die "Cannot lutimes() - $!";

DESCRIPTION
    The regular "chown" system call will dereference a symlink and apply
    ownership changes to the file at which it points. Some OSes provide
    system calls that do not dereference a symlink but instead apply their
    changes directly to the named path, even if that path is a symlink (in
    much the same way that "lstat" will return attributes of a symlink
    rather than the file at which it points).

FUNCTIONS
  $count = lchown $uid, $gid, @paths
    Set the new user or group ownership of the specified paths, without
    dereferencing any symlinks. Passing the value -1 as either the $uid or
    $gid will leave that attribute unchanged. Returns the number of files
    successfully changed.

  $count = lutimes $atime, $mtime, @paths
    Set the access and modification times on the specified paths, without
    dereferencing any symlinks. Passing "undef" as both $atime and $mtime
    will update the times to the current system time.

    Note that for both "lchown" and "lutimes", if more than one path is
    given, if later paths succeed after earlier failures, then the value of
    $! will not be reliable to indicate the nature of the failure. If you
    wish to use $! to report on failures, make sure only to pass one path at
    a time.

TODO
    *   Implement sub-second precision on "lutimes", most likely by taking
        floats or two-element ARRAY refs, similar to "Time::HiRes" uses.
