Library documentation is inside brutus.h.

Build:

	$ ./build	# Builds brutus.o lib and brutus CLI program

ROT13:

	$ echo "Caesar cipher" | ./brutus	# Encode

	Pnrfne pvcure

	$ echo "Pnrfne pvcure" | ./brutus	# Decode

	Caesar cipher

Custom shift:

	$ echo "Caesar cipher" | ./brutus -s 8	# Encode

	Kimaiz kqxpmz

	$ echo "Kimaiz kqxpmz" | ./brutus -s -8	# Decode

	Caesar cipher

By default Brutus shifts using ASCII lower and upper case characters.

You can define custom set of characters called Cipher.

	$ echo "123ab" | ./brutus -c "123456" -s 32	# Encode

	345ab

	$ echo "345ab" | ./brutus -c "123456" -s -32	# Decode

	123ab
