//* Function:     Parse Miranda-NG source for generate translation templates        *//
//* Usage:        Generate translation templates for Miranda-NG plugins and Core    *//
//* Usage:        "cscript /nologo lpgen.js"  to run generation in batches          *//
//* Usage:        "cscript /nologo lpgen.js /log:"yes"" to enable console logging   *//
//* Usage:        "cscript /nologo lpgen.js /path:"path_to_folder"" for one plugin  *//
//* Usage:        "cscript /nologo lpgen.js /crap:"yes"" filtered srings in Crap.txt*//
//* Usage:        Double click to choose folder for one plugin template generation  *//
//* Requirements: for batch mode: create folder ..\..\langpacks\english\Plugins     *//
//* Notes:        ;file path\to\file.ext is a SVN file, source of founded string.   *//
//* Notes:        if double line ;file path\to\file.ext exist, everything from the  *//
//* Notes:        first file was removed as duplicates. You can disable duplicates  *//
//* Notes:        removal by specifying /dupes:"yes"                                *//
