 Possible ticket file format:

-   "WikiPage"
-   parent: UUID*
-   title: TEXT
-   pagename: TEXT
-   mode: (readonly|appendonly|readwrite)
-   attachment: UUID name description
-
-   * Header ends with a blank line.  wiki content follows.
-
-Cluster format:
-
-       M+ uuid
-       Z manifest-cksum
-
-   * Cluster generated in server mode only.
-   * Embargo cluster that reference phantoms or other embargoed clusters.
-   * Never send or ihave an embargoed cluster
-
-New sync algorithm based on clusters:
-
-   * Keep a table of unclustered artifacts.  Strive to keep this table
-     less than 100 entries.
-   * Client sends content of unclustered table as ihaves to server
-   * Server builds a new cluster if size of cluster table >100.
-   * Server sends unclustered table to client
-   * Server sends gimme for all unknown ihave received from client
-   * Client sends gimme for all unknown ihave received from server
-   * Previous two steps repeat until no more gimmes
-
-Details of new push algorithm:
-
-   * Table "unsent" contains all files never pushed
-   * TEMP table "wanted" contains files the server does not have
-   Loop:
-     * Client sends login and "push" record
-     * Client sends file message for all files in unsent and removes
-       those files from the table.
-     * Client sends file message for all files in wanted.
-     * Client sends ihave messages for each entry in unclustered
-     ------
-     * Server receives file message
-     * Server creates phantoms for unknown ihaves
-     * Server sends gimme messages for all phantoms
-     ------
-     * Client clears its unsent table
-     * For each gimme message add an entry to wanted
-     * Halt if the wanted table is empty
-
-Details on new pull algorithm:
-
-   Loop:
-     * Client sends login and "pull" record
-     * Client sends "prior" message with repository id and max record number
-     * Client sends "gimme" for each phantom
-     --------
-     * Server creates new clusters to get unclustered size below 100
-     * If there is "prior" message with repository id that matches this
-       server, then send file messages for all record ids greater than
-       prior
-     * Server sends ihave messages for each entry in unclustered
-     * Server sends maxrid message
-     --------
-     * Client receives file records
-     * Client creates phantoms for unknown ihaves
-     * If no phantoms exist, record maxrid for the server and halt
-
-Need a dephantomize algorithm
-
-
-Auxiliary tables needed for new sync algorithm:
-
-   * unsent:  files that have never been sent to another repository
-   * unclustered: non-phantom files not mentioned by a cluster
