The LangMan component package is used for very simple creation of multilingual applications in Delphi. These components literally relieve you from all the hassle of programming translations, switching languages and maintains full clarity in the source code. Unlike other competing solutions, LangMan is a completely unique and invaluable tool.

You create your application in any base language, regardless of the need for future translation into other languages. Additional languages are then easily added to your application using the built-in localization editor. LangMan components are programmed to save you maximum time in developing your applications.
Tanto package of LangMan Personal components is free for non-commercial localization of VCL applications. Paid versions also support the FireMonkey framework and uniGUI.
