What does Agile stand for?

I have been doing software development using 'Agile' for a few years now. With 'Agile' becoming ubiquitous, what does the Agile stand for? Wikipedia talks a lot about it, but no one can describe it well and to the point than it's founders. Agile Manifesto, as described by it's founders:

We are uncovering better ways of developing
software by doing it and helping others do it.
Through this work we have come to value:

Individuals and interactions over processes & tools
Working software over comprehensive documentation
Customer collaboration over contract negotiation
Responding to change over following a plan

That is, while there is value in the items on
the right, we value the items on the left more.

Anyone who has developed products with small focused teams and startups would fall in love with the above words. I did too :)
