Firebird 2.5 Language Reference in Russian is released

IBSurgeon, in collaboration with Moscow Exchange, became a sponsor of Firebird documentation development in Russian, and our staff has actively participated in writing and editing process. As a result, "Firebird 2.5 Language Reference" in Russian was released (it is available on Firebird Documentation page).  
We plan to support creation of further documentation volumes and its translation to English (it is already available here).
