Option -howtorun allows explicitly specifying how to run <torun>:
script: it is a script file
object: it is an object name
guess: (the default) try to guess
Option -i requests that a file be pre-loaded. It is only
meaningful for interactive shells.
Option -e requests that its argument be executed as Scala code.
Option -savecompiled requests that the compiled script be saved
for future use.
Option -nocompdaemon requests that the fsc offline compiler not be used.
Option -Dproperty=value sets a Java system property.
