The AStyle Beautifier Plugin formats and beautifies Java, C and C++ source code, using a platform independent version of Artistic Style (also known as astyle), the Open Source Code Beautifier, written by Tal Davidson (see http://astyle.sf.net). The plugin optionally formats source code automatically, when the current buffer is saved. For this to work, the buffer must be in "java", "c" or "c++" mode.
