fbsql aims to ease the use of Firebird and Interbase databases by providing clean client libraries for different languages. The raw Firebird/Interbase API is very awkward and hard to work with, while fbsql is easy and straightforward, like the sqlite and MySQL APIs. Currently C and Lisp are supported. fbsql uses IBPP, a C++ Interbase/Firebird API for its implementation. It's basically just a thin wrapper around IBPP to make it accessible in C.
