LangFile.nsh

Header file to create langauge files that can be
included with a single command.

Copyright 2008-2009 Joost Verburg

* Either LANGFILE_INCLUDE or LANGFILE_INCLUDE_WITHDEFAULT
  can be called from the script to include a language
  file.

  - LANGFILE_INCLUDE takes the language file name as parameter.
  - LANGFILE_INCLUDE_WITHDEFAULT takes as additional second
    parameter the default language file to load missing strings
    from.

* A language file start with:
  !insertmacro LANGFILE_EXT "English"
  using the same name as the standard NSIS language file.

* Language strings in the language file have the format:
  ${LangFileString} LANGSTRING_NAME "Text"
