GlideinWMS

Ask Jeff how this was used:

This one we do use a lot, to propagate changes from one factory config file to another. 
Here's a basic example:
$GLIDEIN_SRC_DIR/creation/clone_glidein -other glideinWMS.xml.ucsd 
                                        -out glideinWMS.xml.test 
                                        -merge only 
                                        -exclude name CMS_T2_US_Nebraska 
                                        -exclude name CMS_T2_US_UCSD glideinWMS.xml

The config in -other is the one you want to pull updates from.  -out specifies the name of 
the newly generated config.  In this example we are telling the clone tool to ignore a few 
entries with the -exclude option.  finally the last config file listed here is the original 
you want to base it on.

-merge only here means, only propagate changes into glideinWMS.xml.test and don't add new 
entries.  Other possible options for -merge:
    yes - modify existing entries in addition to adding new ones
    no - only add new entries

There are a few options we use less often but if you want to know how they work I may 
remember.
