+|| Sysel Bootstrap Interpreter (SBI) || In progress  || Interpreter of Sysel written in C. Runs in HelenOS and POSIX. ||

+== SBI ==
+
+SBI is an interpreter of Sysel currently in development. It is available stand-alone for POSIX or integrated in HelenOS (only in Bazaar repository, not yet in a stable release). You can run it with the command "`sbi `''source_file.sy''". Demos that you can run are available in `/src/sysel/demos`. Source files comprising the library are in `/src/sysel/lib`.
+
+You can also run `sbi` without parameters to enter interactive mode.
+
+=== Synopsis of current SBI features ===
+
+ * Primitive types: bool, char, int, string
+ * Compound types: class, multi-dimensional array
+ * Objective features: inheritance, grandfather class, static and non-static method invocation
+ * Syntactic sugar: variadic functions, accessor methods (named and indexed)
+ * Arithmetic: big integers, addition, subtraction, multiplication
+ * Static type checking (mostly), Exception handling
+ * Bindings: Text file I/O, !WriteLine, Exec
+
+=== Missing SBI features ===
+
+ * division
+ * boolean operations (and, or, not)
+ * structs
+ * interfaces
+ * builtin object methods/properties
+ * auto-boxing
+ * static/nonstatic checking
+ * static class variables
+
+ * generic types
+ * method and operator overloading
+ * packaging
