1.1     ! casties     1: Source Syncer
        !             2: -------------
        !             3: 
        !             4: Source Syncer is an Open Source product from ZeOmega that allows live zope
        !             5: objects to be synchronized from one Zope Instance to another without going
        !             6: through the tedious export / transfer / import procedure. It is very easy to
        !             7: use and also provides very robust security and access control, so that it can
        !             8: be used for synchronization between zope development and production sites. It
        !             9: has the ability to view at a glance which objects are out-of sync and also
        !            10: allows you to view a color coded diff against the destination object, for many
        !            11: types of objects.
        !            12: 
        !            13: Methodology
        !            14: ------------
        !            15: 
        !            16: It uses message digests to detect changes in object bodies that is returned
        !            17: using the objects document_src() method. So the entire source is not sent
        !            18: across the network ,instead the message digest is created and sent which is
        !            19: relatively small insize.Thus detecting the differences between source and
        !            20: destination is done with very little overhead and suitable for highlatency
        !            21: networks . A primary difference between the Source Syncer and the ZSyncer
        !            22: product, which is also used for code sync is that, Source Syncer does not
        !            23: depend on time stamps and most importantly syncs only the source and not the
        !            24: entire object. So Objects at either end continue to retain all other
        !            25: attributes. This is very useful when production objects have properties set on
        !            26: them that should NOT be changed.  It also works when the source and
        !            27: destination servers are at different time zones as content editors may not be
        !            28: working in the same time zone as the production servers. It uses xml-rpc and
        !            29: supports SSL as well as non-secure HTTP. It reuses a lot of code for network
        !            30: communication from the original ZSyncer product.
        !            31: 
        !            32: 
        !            33: Installation
        !            34: ------------
        !            35: 
        !            36: Place the VSyncer directory in your zope Products directory as usual with
        !            37: product installation. You need to do this for all Zope servers that you wish
        !            38: to use as sources or destinations. Be sure that you can make HTTP connections
        !            39: from the source server to the destination server (and the Zope port). Source
        !            40: Syncer cannot work without this.The managers id that is used in the source,
        !            41: should have a login id on destination with the same password.
        !            42:
