1. install indent. (for linux, rpm is available from standard distribution.)
2. save file .indent.pro to your home directory.
3. say you have a file called "foo.C", run indent like this: indent foo.C
   
4. because indent is designed for C code, it is not perfect for C++ code. Read your new source and fix the following possible errors:

• change 'const const' to 'const'
