In fact, prototype are separate files. They are just put together for the release. See http://dev.conio.net/repos/prototype/src/ for the single files. 2005/11/16, Richard Archer <drupal.org@juggernaut.com.au>:

Prototype does indeed seem to be a very light, clean, and extensible library: but nonetheless, it is nowhere near as light as drupal.js. Quick comparison:

Drupal.js: 281 lines, 6.21KB Prototype.js: 1039 lines, 27.29KB

All the Drupal .js files combines come to 18 kB.

Is it possible to strip prototype down a bit?

There are a lot of comments in the file that wouldn't be needed in a live site.

What about separating it into function-related files and just sending the bits the page needs?
