Compress your minified JavaScript even further!
Uses a fast token-replacement algorithm to squish your JavaScript down.
Meant to be used after a minify tool.
For jQuery 1.9.1, its minified size is 92,629 bytes.
After squishing, it is 80,556 bytes.
(16.63% savings.)
A copy of the original and squished is in extern/.
Running performance is the same, but the squished version seems to take about twice as long to load. (Tested for jQuery on Chrome 26 on OS X.)

If your web server gzips automatically, you still can still shave a few more percentage points
off.
For jQuery 1.9.1 again, the gzipped, minified size is 32,704 (32,656 with -9).
After squishing, this comes down to 32,257 (32,220 with -9).
(1.37% savings, 1.34% with -9.)
cd tests ./tests.sh
Python 2.7+. Should also work in Python 3.2+.
Needs v8 for tests.
