NAME
       xbssnapshot - CoreXBS snapshot utility

SYNOPSIS
       xbssnapshot fetch [--[no]live] [--age hours] [--[no]xpc] train_name

       xbssnapshot authcheck [--timeout seconds] train_name

DESCRIPTION
       In  the	1st  form,  xbssnapshot  is used to obtain a snapshot of Cortex for train_name. A cache of snapshots is maintained in a directory,
       which may or may not be used in addition to consulting the Cortex servers depending on command line OPTIONS  specified.	If  successful,  a
       file URL of a suitable snasphot is printed to STDOUT. On failure, a description of the failure is printed to STDERR.

       In  the	2nd  form,  xbssnapshot  is  used to check connectivity to the Cortex servers for train_name and determine if AppleConnect (Single
       Sign-On) credentials will be required to obtain a snapshot. If the Cortex server can be reached, YES is printed to STDOUT if SSO  authenti-
       cation  is required and NO is printed if not. On failure (including not being able to reach the Cortex servers), a description of the fail-
       ure is printed to STDERR.

OPTIONS
       --live Force xbssnapshot to bypass the snapshot cache directory and fetch data from Cortex.

       --nolive
	      Force xbssnapshot to not fetch data from Cortex and only use the snapshot cache directory.

       --age hours
	      When considering if a snapshot found in the snapshot cache directory is "new enough", only accept snapshots that are less than hours
	      old.

       --xpc  Use XPC service when fetching data from Cortex. This is the default.

       --noxpc
	      Bypass XPC service when fetching data from Cortex.

       --timeout seconds
	      When performing connectivity test with Cortex server(s), how long to wait before assuming no connectivity to a given Cortex server.

RETURN VALUES
       Returns 0 on success, and non-zero on failure.

ENVIRONMENT
       CTXHost
	      May be set to the hostname of a specific Cortex server. This is mainly only useful to the developers.

       CTXPort
	      May  be  set  to specific port to connect to CTXHost on (does nothing unless CTXHost is also set). This is mainly only useful to the
	      developers.

FILES
       /Library/Caches/com.apple.bni.cortexsnapshot
	      Directory where snapshots are cached.

       /var/log/system.log
	      CoreXBS framework and XPC services log here. grep CoreXBS /var/log/system.log may show additional information above and beyond  what
	      xbssnapshot prints on it's own.
