Just sit right back and you'll hear a tale,
A tale of a fateful trip
That started from this tropic port,
Aboard this tiny Ship.  ....

That's about it. We also tend to be academics.

They are fluid, but we try to be somewhat careful with backwards
compatibility. In major releases, there are often major changes and we
provide porting guides (and sometimes backwards compatible macros are
possible to help with that). We've been thru 4 of those in the last 14
or so years.

It supports many. This is not an exclusive or. :)

I think that the Scheme cookbook (http://schemecookbook.org/) is the
closest thing. There are also user-contributed libraries on PLaneT
(http://planet.plt-scheme.org/), which plays some of the role those
would play. See also http://www.plt-scheme.org/community.html .
