Intlize allows the developer to use catgets without its normally bulky syntax and without having to mind the details of correct indices. Catgets is the built-in internationalization suite of C compilers. Alternatively, Intlize can produce a compact file format optimized for fast access. Intermediate files are in gettext po format, so there are many comfortable tools available to do the translations. Runtime files are provided for C and C++ and for both catgets and intlize native support.
