vi and code beautify

[der.hans]

moin, moin,

do any of the vi clones have a way to re-indent code?

I know emacs has something, but have only used it once or twice.

I want to be able to automagically reindent a block.

Say I add an if statement, I want to automagically be able to toss
everything that it now surrounds in one more tab.

e.g.:

if ( $fred ) {
&do_the_fred;
}

becomes:

if ( $fred ) {
	&do_the_fred;
}

This hopefully works for multiple languages. I'll worry about particulars
such as brace placement after I have something already working :).

ciao,

der.hans
