CODE STYLE

In order to keep the code nice and clean we have a few requirements you'll
need to stick to in order to get your patch accepted:

- use 4 spaces for indentation
- use 80 columns max
- use unix-style end-of-lines (all decent win32 editors support it)
- use definition-block brackets on a new line and command-block brackets
  on the same line
- use spaces between expression operators ("i + 1" instead of "i+1")

To check wheter your code complies with our standard, you may use the tool
"astyle". Make sure you use the following options:

  prompt-$ astyle --indent=spaces=4 --brackets=linux --indent-labels \
           --pad=oper --one-line=keep-statements --convert-tabs \
           --indent-preprocessor file.cc
  prompt-$ diff file.cc file.cc.orig

VIM USERS

If you use the VIM editor, you may add the following line to you ".vimrc"
configuration file to automatically setup your editor to use opencog's style
when editing a source file from opencog's tree:

autocmd BufNewFile,BufReadPost * if match(expand("%:p:h"), "/opencog") >= 0 && &filetype == "cpp" | set ts=4 sw=4 tw=80 ff=unix cindent expandtab | endif

EMACS USERS

If you use Emacs, you may add the following lines to your ".emacs" as well:

(setq-default indent-tabs-mode nil) ;; use spaces instead of tab
(setq-default c-basic-offset 4) ;; set c based language indent to 4
