Starts ikarus in r6rs-script mode. The script file is treated\n\

as an R6RS-script. The options opts ... can be obtained using\n\

the \"command-line\" procedure in the (rnrs programs) library.\n\

|
Starts ikarus in interactive mode. Each of the files is first\n\

loaded into the interaction environment before the interactive\n\
|
|
repl is started. The options opts can be obtained using the\n\
|
|
\"command-line\" procedure.\n\

If the option [-b <bootfile>] is provided, the bootfile is used\n\
|

as the system's initial boot file from which the environment is\n\
|
|
initialized. If the -b option is not supplied, the default boot\n\
|
|
file is used. The current default boot file location is\n\
|

\"%s\".\n\
