vim commenting -- NERD Commenter plugin

Here's a link to a pretty good vim commenting plugin [by the name NERD Commenter]: link.

The page has basic functionality explanation, supported file types, how-to install and download links (in that order[;)])

In case you are not so good at hacking vimrc fileor making your own commenting scripts (like me), use this. Even if you can do the above, this might work better at less effort -- as they say, Do not do for yourself what somebody else can do for you ;).

Extract the archive to your ~/.vim/ directory
If you want to integrate the help (doc) of the plugin with vim's do
:helptags ~/.vim/doc
within vim....
