-Arduino/lib/targets/libraries folder.
-
-When installed, this library should look like:
-
-Arduino/lib/targets/libraries/Test              (this library's folder)
-Arduino/lib/targets/libraries/Test/Test.cpp     (the library implementation file)
-Arduino/lib/targets/libraries/Test/Test.h       (the library description file)
-Arduino/lib/targets/libraries/Test/keywords.txt (the syntax coloring file)
-Arduino/lib/targets/libraries/Test/examples     (the examples in the "open" menu)
-Arduino/lib/targets/libraries/Test/readme.txt   (this file)
-
-Building
---------------------------------------------------------------------------------
-
-After this library is installed, you just have to start the Arduino application.
-You may see a few warning messages as it's built.
-
-To use this library in a sketch, go to the Sketch | Import Library menu and
-select Test.  This will add a corresponding line to the top of your sketch:
-#include <Test.h>
-
-To stop using this library, delete that line from your sketch.
-
-Geeky information:
-After a successful build of this library, a new file named "Test.o" will appear
-in "Arduino/lib/targets/libraries/Test". This file is the built/compiled library
-code.
-
-If you choose to modify the code for this library (i.e. "Test.cpp" or "Test.h"),
-then you must first 'unbuild' this library by deleting the "Test.o" file. The
-new "Test.o" with your code will appear after the next press of "verify"
