VSCM: Portable R4RS Scheme implementation.

VSCM is a portable R4RS Scheme. The implementation is based on a virtual machine design with heavy support for most of the sophisticated features of Scheme. The virtual machine is written in ANSI-C to aid in its portability. The bytecode compiler is written in Scheme itself. Extensions to R4RS include: - ability to create a memory image of a running VSCM (dump) - ability to execute a shell command (system) - continuations with multiple arguments (call-with-values) - error handling (with-error-handler) - flexible garbage collection (with-gc-strategy) - interrupts (with-interrupt-handler) - errors (error) - CPU time measurements (clock, gc-clock, timer) - access to the environment (getenv) - eval - control over open compilation - file system interface (remove-file, rename-file, etc.) - generic ports - writing to and reading from strings - property lists
