Why it is only in Russian and how to get it in English? The answer is the following: Moscow Exchange, one of the biggest Firebird users in the world, and IBSurgeon (tools and service for Firebird) have sponsored documentation development in Russian. Several Russian-speaking core developers of Firebird Project participated in documentation creation to ensure its quality.
The next step is extending this documentation to cover Firebird 3 new features: authors and editors are already working on it. However, the resulted documentation for Firebird 3 will be also in Russian.
In order to translate Firebird documentation into English, Firebird Project needs additional funds.
We need US$7000 to translate almost 500 pages of Firebird documentation into English using professional translation service, which will ensure the quality of translation.
So, if you would like to have Firebird 2.5 and 3.0 Language Reference in English in the first quarter of 2015, please help Firebird Project now with your donations (please use PayPal option): http://www.firebirdsql.org/en/donate/
Please don’t think that somebody else will pay for Firebird documentation!
Collected money will go to translation of Firebird documentation and, if USD$ 7000 threshold will be exceeded, for further development of next volumes: Firebird Operations Guide and others.
