When a sketch has unsaved changes, a temporary copy of the sketch is made with those changes applied. This copy is then passed to arduino-builder. Previously, this temporary copy was kept around and only deleted when the IDE was closed. However, all files were written to it again on every build, so keeping the old files around did not serve any real purpose. When a file was renamed in the IDE, the original name would still be present in the temporary copy, and could cause linker errors because both were compiled. This commit makes sure the temporary copy is deleted after every build, instead of at IDE exit, which fixes this problem with renames. When a file is deleted from the sketch, the file would also be deleted from the temporary copy, presumably to fix this same problem for deletes (but renames were forgotten). With this commit, this special handling for deleting files is no longer needed, so it is removed. This fixes #4335

Arduino is an open-source physical computing platform based on a simple i/o board and a development environment that implements the Processing/Wiring language. Arduino can be used to develop stand-alone interactive objects or can be connected to software on your computer (e.g. Flash, Processing, MaxMSP). The boards can be assembled by hand or purchased preassembled; the open-source IDE can be downloaded for free at http://www.arduino.cc/en/Main/Software

More complex requests and technical discussion should go on the Arduino Developers mailing list: https://groups.google.com/a/arduino.cc/forum/#!forum/developers

If you're interested in modifying or extending the Arduino software, we strongly suggest discussing your ideas on the Developers mailing list before starting to work on them. That way you can coordinate with the Arduino Team and others, giving your work a higher chance of being integrated into the official release https://groups.google.com/a/arduino.cc/forum/#!forum/developers
Installation
Detailed instructions are in reference/Guide_Windows.html and reference/Guide_MacOSX.html. For Linux, see the Arduino playground: http://www.arduino.cc/playground/Learning/Linux
Credits
Arduino is an open source project, supported by many.
The Arduino team is composed of Massimo Banzi, David Cuartielles, Tom Igoe and David A. Mellis.
Arduino uses GNU avr-gcc toolchain, GCC ARM Embedded toolchain, avr-libc, avrdude, bossac, openOCD and code from Processing and Wiring.
