Dictionary Specification Language
Starting with version 6.0, ABBYY Lingvo includes a DSL compiler (Dslcomp.exe in the Lingvo folder) that can be used to create new dictionaries which can be seamlessly integrated into the Lingvo Bookshelf. You can share such dictionaries with your friends and colleagues or even with the whole Lingvo community at www.lingvo.ru.
Using the DSL Compiler users can create cards that have the same look and feel as cards from the system dictionaries.
Unlike custom dictionaries that can be created and updated directly from Lingvo, DSL dictionaries are created using an external text editor and are then compiled.
