HSPlet
HSPlet is a framework for running Hot Soup Processor applications on the Java platform, as applets. HSPlet is written by Group Finity. The current release is 3.0.1.2.
HSPlet takes HSP bytecode (PACKFILEs, such as start.ax) and interprets it to call into the Object Web ASM Java bytecode manipulation framework to generate a class. This class is linked against the HSPlet runtime library.
