    I am a path on the filesystem that only permits 'downwards' access.

    Instantiate me with a pathname (for example,
    FilePath('/home/myuser/public_html')) and I will attempt to only provide
    access to files which reside inside that path.  I may be a path to a file,
    a directory, or a file which does not exist.

    The correct way to use me is to instantiate me, and then do ALL filesystem
    access through me.  In other words, do not import the 'os' module; if you
    need to open a file, call my 'open' method.  If you need to list a
    directory, call my 'path' method.

    Even if you pass me a relative path, I will convert that to an absolute
    path internally.

    Note: although time-related methods do return floating-point results, they
    may still be only second resolution depending on the platform and the last
    value passed to L{os.stat_float_times}.  If you want greater-than-second
    precision, call C{os.stat_float_times(True)}, or use Python 2.5.
    Greater-than-second precision is only available in Windows on Python2.5 and
    later.

        the filesystem that this L{FilePath} points to.  This attribute is

        L{FilePath.changed} indicated that new information is required), 0 if
        C{stat()} was called and returned an error (i.e. the path did not exist
        when C{stat()} was called), or a C{stat_result} object that describes
        the last known status of the underlying file (or directory, as the case
        may be).  Trust me when I tell you that you do not want to use this
        attribute.  Instead, use the methods on L{FilePath} which give you

        Replace the file at this path with a new file that contains the given
        bytes, trying to avoid data-loss in the meanwhile.

        On UNIX-like platforms, this method does its best to ensure that by the
        time this method returns, either the old contents I{or} the new contents
        of the file will be present at this path for subsequent readers
        regardless of premature device removal, program crash, or power loss,
        making the following assumptions:

            - your filesystem is journaled (i.e. your filesystem will not
              I{itself} lose data due to power loss)

            - your filesystem's C{rename()} is atomic

            - your filesystem will not discard new data while preserving new
              metadata (see U{http://mjg59.livejournal.com/108257.html} for more
              detail)

        On most versions of Windows there is no atomic C{rename()} (see
        U{http://bit.ly/win32-overwrite} for more information), so this method
        is slightly less helpful.  There is a small window where the file at
        this path may be deleted before the new file is moved to replace it:
        however, the new file will be fully written and flushed beforehand so in
        the unlikely event that there is a crash at that point, it should be
        possible for the user to manually recover the new version of their data.
        In the future, Twisted will support atomic file moves on those versions
        of Windows which I{do} support them: see U{Twisted ticket
        3004<http://twistedmatrix.com/trac/ticket/3004>}.

        This method should be safe for use by multiple concurrent processes, but
        note that it is not easy to predict which process's contents will
        ultimately end up on disk if they invoke this method at close to the
        same time.

        @param ext: An extension to append to the temporary filename used to
            store the bytes while they are being written.  This can be used to

        Copies self to destination.

        If self doesn't exist, an OSError is raised.

        If self is a directory, this method copies its children (but not
        itself) recursively to destination - if destination does not exist as a
        directory, this method creates it.  If destination is a file, an
        IOError will be raised.

        If self is a file, this method copies it to destination.  If
        destination is a file, this method overwrites it.  If destination is a
        directory, an IOError will be raised.

        If self is a link (and followLinks is False), self will be copied
        over as a new symlink with the same target as returned by os.readlink.
        That means that if it is absolute, both the old and new symlink will
        link to the same thing.  If it's relative, then perhaps not (and
        it's also possible that this relative link will be broken).

        File/directory permissions and ownership will NOT be copied over.

        If followLinks is True, symlinks are followed so that they're treated
        as their targets.  In other words, if self is a link, the link's target
        will be copied.  If destination is a link, self will be copied to the
        destination's target (the actual destination will be destination's
        target).  Symlinks under self (if self is a directory) will be
        followed and its target's children be copied recursively.

        If followLinks is False, symlinks will be copied over as symlinks.

            should be copied
