There are a few :help entries on folding, which can be found by e.g. :help
fold<tab> but :help foldmethod (or fdm) is probably the most useful.

I usually set it to 'marker' and add folds manually by putting {{{
}}} around whatever I want folded:

// {{{
<lines of code here>
// }}}

Then you can use a bind such as 'za' to open/close the fold. Change
'//' to whatever comment character(s) your code uses.

You can also add text after the fold lines - e.g.

// {{{ Function description

There are a bunch of different maps that work on folds - see :help
fold-commands.

Another useful one is foldenable (fen). If you set it in your
~/.vimrc it makes all folds closed when you open a file with folds
for the first time.

I forgot to mention an important fact in the 1.3.67 announcement. In order to
get a fully working kernel, you have to follow the steps below:
- Walk around your computer widdershins 3 times, chanting "Linus is
overworked, and he makes lousy patches, but we love him anyway". Get
your spuouse to do this too for extra effect. Children are optional.
- Apply the patch included in this mail
- Call your system "Super-67", and don't forget to unapply the patch
before you later applying the official 1.3.68 patch.
- reboot
