1. SQL database and parser generator in Python Gadfly is a relational database management system which uses a large subset of very standard SQL as its query language and Python modules and optional Python/C extension modules as its underlying engine. Gadfly stores the active database in memory, with recovery logging to a file system. It supports an optional TCP/IP based client server mode and log based failure recovery for system or software failures (but not for disk failures). kwParser, included as part of the Gadfly package, is a parser generator for Python. It transforms an abstract specification of a language grammar (for example the CORBA Interface Definition Language) together with "interpretation functions" that define the semantics of the language into a compiler or translator or interpreter.
