[JW Lua] Reading the path/filename of the current plugin

[Jan Angermüller]

Jari,

it's possible to read the general Finale plug-in path with FCString.
But is it also possible to read the plug-in path of the current JW Lua 
script ?
And maybe even its filename ?
I.e.
c:\program files\Finale 2012\Plug-ins    (general Finale plug-in path)
compared to
c:\program files\Finale 2012\Plug-ins\jw lua scripts\                   
(lua script path)
c:\program files\Finale 2012\Plug-ins\jw lua scripts\copylayers.lua (lua 
script)

I am asking because I want to read/save ini-files for the plug-ins.
And - if possible - those should be found in the same directory as the 
plug-in script.

Best regards,
Jan
