27 \ingroup Roostats
28
29Holds configuration options for proof and proof-lite.
30
31This class will be expanded in the future to hold more specific configuration
32options for the tools in RooStats.
33
34Access to TProof::Mgr for configuration is still possible as usual
35(e.g. to set Root Version to be used on workers). You can do:
36
37~~~ {.cpp}
38 TProof::Mgr("my.server.url")->ShowROOTVersions()
39 TProof::Mgr("my.server.url")->SetROOTVersion("v5-27-06_dbg")
40~~~
