How to write PEP8 compliant Python code on Vim

I've made this code two years ago when I wrote code for one of the popular open cloud program. This is not a standard plugin code for vim, If you have not made any configurations, you can simply follow the instructions here and download this code. This is for Ubuntu and Debian only.
I've made this seeing two links, which I don't remember right now. Sorry about that.

Please download this code (https://app.box.com/s/plc7xwm49avp4ubzq915) and follow these instructions

This is tutorial is for people who are already little known to vi editor. This is  done for vim 7.2
vim for terminal

The vimrc is so set that it would not let  write code beyond 80 lines and would automatically break. using   will
throw all the pep8 errors

Installation
-------------
Install vim7.2
Ubuntu: sudo apt-get install pep8
Ubuntu : sudo apt-get install vim
Ubuntu : sudo apt-get install vim-common (you may not need this step on all Ubuntu's)
Ubuntu : sudo apt-get install vim-runtime (you may not need this step on all Ubuntu's)
Ubuntu : sudo apt-get install vim-tiny (you may not need this step on all Ubuntu's)
copy the .vimrc from the folder to your  /home/yourusername/.vimrc
copy the folder .vim to  /home/yourusername/.vim

Checking PEP8 Complaint

ctags -R -f ~/.vim/tags/python.ctags /usr/lib/your_python_library/  /home/youruser/any-python-project1/ /home/youruser/any-python-project2/ .. so on

Browsing the source code of the file
-------------------------------------

in ex-mode

Command in Ex-mode  - Functionality

F5 -  would run pep8 command would show list of pep8 errors (this happens only on all .py files)

Question: Mac grep to exclude directories

I'm tired of searching for this exclude directories apparently running grep -ir --exclude-dir=.svn  'needle' . on Mac OS X snow leopard . The --exclude-dir for grep does not work on Mac. Also I don't want to run any piped greps like  "grep -nHR 'needle' . | grep -v svn" as I'm searching in a 30GB source code as it consumes too many hours.

Coding on Open Source Products

Well, I've been working on LAMP(Linux, Apache, MySQL and PHP) for past three plus years. I thought I should write a technology blog, and chose PHP technology with which I work.

The two Open sources that I started working have enhanced my coding skills. First one being dotproject, The second one being wordpress. Most well known opensource products for Project Management and Blogging tools respectively.

Though these two are indifferent products they use same technology in PHP Both use PHP as the language.MySQL being the common database for most of opensource products. The other two being OS and Webserver whom generally being Linux and Apache.

Unlike the commercial products ,these products surpass them in their reusing the code(OOPS in PHP), PHP-coding perspective,PHP -designing perspective,PHP-security and building the product. Gives a very good start for those who starters coding on a product with PHP as their technology. The method of designing, coding, reusing is something to be learnt from them.

Dotproject uses MVC(Model View Contoller)design pattern while wordpress uses singleton pattern. Apart from designing usage of some other utility softwares in these products like ,ez2pdf, ADOdb, PEAR libraries etc gives more deep insight of how to use a third party tools.
