Usage: isabelle process [OPTIONS]
Options are:
-T THEORY load theory
-d DIR include session directory
-e ML_EXPR evaluate ML expression on startup
-f ML_FILE evaluate ML file on startup
-l NAME logic session name (default ISABELLE_LOGIC=""" + quote(logic) + """)
-m MODE add print mode for output
-o OPTION override Isabelle system OPTION (via NAME=VAL or NAME)
Run the raw Isabelle ML process in batch mode.
