Execute logon macro's.
There are three levels of logon macros that will be executed: the system logon etc/system.rootlogon.C, the global user logon ~/.rootlogon.C and the local ./.rootlogon.C. For backward compatibility also the logon macro as specified by the Rint.Logon environment setting, by default ./rootlogon.C, will be executed. No logon macros will be executed when the system is started with the -n option.

Calls ProcessLine() possibly prepending a line directive for better diagnostics.
Must be called after fNcmd has been increased for the next line.
Process the content of a line starting with ".R" (already stripped-off) The format is [user@]host[:dir] [-l user] [-d dbg] [script] The variable 'dir' is the remote directory to be used as working dir.
The username can be specified in two ways, "-l" having the priority (as in ssh). A 'dbg' value > 0 gives increasing verbosity. The last argument 'script' allows to specify an alternative script to be executed remotely to startup the session.
Reimplemented from TApplication.
Main application eventloop.
First process files given on the command line and then go into the main application event loop, unless the -q command line option was specified in which case the program terminates. When return is true this method returns even when -q was specified.
When QuitOpt is true and return is false, terminate the application with an error code equal to either the ProcessLine error (if any) or the return value of the command casted to a long.
