    XC Watcher and Configurator
    
    Configurator is a utility that can be used to setup a Postgres-XC cluster
    automatically. Based on Ruby and a global YAML configuration file, it is in charge of
    parsing the global file, make postgresql.conf, indent and pg_hba.conf,
    and then distribute each postgreSQL file automatically to each node.
    
    XC watcher is a module using XCM flag information to gather the status of nodes
    in the cluster and what kind of action is necessary in case a node fails.
    This module takes into account Datanode, Coordinator, GTM, GTM-Proxy and GTM-Standby.

    This is the second commit of Postgres-XC documentation.   Contents of the commit is as follows:
    
    1) For sections just from PostgreSQL and not reviewd yet, added notice that this need further review and revision.  Notice will be found in the file pgnotice.sgmlin.
    
    2) First revision work on "installation".   This is still WIP.
    
    To include notice in 1) almost all the files are modified.   So far, we can generate html and man with this commit.
