 See documentation for more information about the following functions.

 Usage in script:
 1. !include "TextFunc.nsh"
 2. [Section|Function]
      ${TextFunction} "File" "..."  $var
    [SectionEnd|FunctionEnd]


 TextFunction=[LineFind|LineRead|FileReadFromEnd|LineSum|FileJoin|
               TextCompare|TextCompareS|ConfigRead|ConfigReadS|
               ConfigWrite|ConfigWriteS|FileRecode|TrimNewLines]
