	# make all-         Calls compile, certificate, jar, and javadoc.
	# make compile-     Remakes the class files.
	# make certificate- Remakes the certificate (certificates expire in
	#                       about 3 months for some reason).
	# make jar-         Repacks and signs the jar file.
	# make permissions- Resets the permissions of all files in the project
	#                       folder to 775.
