Switch to set view when opening logs in CMtrace.
A switch to pass when opening multiple log files in CMtrace via command line. Example: you want to monitor a client install, so you want to open ccmsetup.log and client.msi.log.
Something like cmtrace <path to file1>,<path to file2> -Vertical
or cmtrace <path to file1>,<path to file2> -Horizontal
