Dear Jonathan,

Is          /config/scripts-library/       ok?

Or would you prefer  /config/scripts/scripts-library/

If there is no :-

// TeXworksScript
// Title: dah dah ...

Then such scripts libraries.js would not be read into the Scripts menu
if in /config/scripts/scripts-library/  ?

Revised, removed path delimiter change, moved some variables to global
for reuse in sucessive function calls.


/////////////////////////////  Begin Preamble  \\\\\\\\\\\\\\\\\\\\\\\\\	
  var libraryPath;

  var scriptsHere = __FILE__.lastIndexOf("/scripts/");
     libraryPath = __FILE__.substr(0,scriptsHere) + "/scripts-library/";
		 //   /script-library/ is a sibling to /scripts/ just below /config/
function getLibrary(libraryName)
	var thisLibrary = libraryPath + libraryName +".js";

// temporary workaround as their may be a new function "readFile()" available			
	var libraryOpened = 	TW.app.openFile(thisLibrary);
  var Js = libraryOpened.text;
              libraryOpened = null;
 // sucessive libaries can be called this way.			
/////////////////////////////  End Preamble  \\\\\\\\\\\\\\\\\\\\\\\\\
