Is there an Emacs alternative to Pathogen from Vim?

I am trying to move from Vim to Emacs and have had some "translation" issues. For example the extension or add on managing. So I was wondering if there was something like pathogen for Emacs although I am very suspicious of the fact that perhaps there isn't one because the way Emacs handles it's extensions it is not needed. I think this has been my only quirk with the editor so far. Other than that I can notice the different approaches of both tools and realize that they excel in what they are supposed to do. Thanks!

EDIT: Right. What pathogen does is manage Vim extensions by loading them as "Bundles" instead of having 开发者_高级运维each file on a different folder inside your .vim folder. You have it centralized and autoloaded by pathogen itself.

From emacswiki,

package.el (from ELPA) will be added to vanilla GnuEmacs, version 24. As of 2010-06-18, package.el has been merged with the development version of Emacs, and an ELPA repository has been set up at http://elpa.gnu.org/.

el-get is another option.
