Reva: Command-line

-c directory	Switch (chdir) to the specified directory after Reva has loaded.
-n library	Include a library (i.e., `needs`). The argument to the -n switch specifies the path to a file in Reva's 'lib' directory or its subdirectories.
	Ex: reva -n alg/structs
-d	Include the debugger library (an abbreviated alternative to `-n debugger`). The debugger library includes the ability to `see` disassembled code for words (rather than just providing a hex dump), and also provides some advanced debugging options such as setting breakpoints and inspecting register contents.
-e code	Execute some Forth code after Reva has loaded. If the code contains spaces, it must either be quoted or the spaces escaped.
-a	Include ANSI compatibility.
-t	Enable testing mode after Reva has loaded.
-v	Print the Reva version and exit.
