Beautify your c/c++ source code

http://uncrustify.sourceforge.net/

• Ident code, aligning on parens, assignments, etc
• Align on '=' and variable definitions
• Align structure initializers
• Align #define stuff
• Align backslash-newline stuff
• Reformat comments (a little bit)
• Fix inter-character spacing
• Add or remove parens on return statements
• Add or remove braces on single-statement if/do/while/for statements
• Supports embedded SQL 'EXEC SQL' stuff
• Highly configurable - 385 configurable options as of version 0.56
