Detailed Description

Syntax:
    ExtracAppInfoFromXML [-sapc] file
Parameters:
    file    file from where to read a RCMS configuration
    -s      list application servers found in the XML file
    -p      list the ports used found in the XML file
    -a      list the names of the applications configured in the XML file
    -c      list the cfg (eg dqmfu09-1_cfg.py) files
Notes:  
    The default behavior is to present a table organized in the following way
        SERVER PORT CFG_FILE APP_NAME
    which is equivalent to using -sapc
    
    The options selected and their order will affect teeh fields shown and their
    respective sorting. eg.
        -sa will only show SERVER and APP_NAME and will sort first by SERVER and
         then by APP_NAME 
         
    OUTPUT is always unique in a per row bases

getAppInfo #

getAppInfo(XMLf,s=0,a=2,p=1,c=3) takes the file name of a valid RCMS 
    configuration and 4 variables that represent which fields are desired 
    and in which order. 
    
    It returns a touple containing a directory that contains all the 
    relevant information in the XMLf file and a list of rows each row 
    containing the fiels specified by the other four variables in the r
    espective order
    
    The fields are Servers (s) ports(p) Appnames a.k.a. consumer names(a) 
    and consumer config file. (Note: The consumerName is directly extracted 
    from the config file.) if one field is not desired it should be assigned
    a value of -1 eg s=-1. other wise their value is mapped from smallest to
    largest ==> left to right. Note the default values, they will take 
    precedence if not specifyed giving unexpected results
