SableVM implements the Java virtual machine specification, second edition.

SableVM is a bytecode interpreter. It's goals are to be reasonably small,
efficient, and fast, as well as providing a well-designed platform for
doing research into different algorithms for bytecode interpretation,
garbage collection, memory management, etc.

SableVM uses a modified version of the GNU Classpath Java classes;
these classes are installed by the "sablepath" port.

+SableVM implements the Java virtual machine specification, second edition.
+
+SableVM is a bytecode interpreter. It's goals are to be reasonably small,
+efficient, and fast, as well as providing a well-designed platform for
+doing research into different algorithms for bytecode interpretation,
+garbage collection, memory management, etc.
+
+SableVM uses a modified version of the GNU Classpath Java classes;
+these classes are installed by the "sablepath" port.
