[Chicken-users] Expecption Handling with chicken

[Michael Erdmann]

Dear all,

i am a little bit confused. The documentation i got together
with 1.66 says there is an execpteion handling available
according to srfi-12.
When i am calling (CURRENT-EXCEPTION-HANDLER) the function is not
known.
Do i need to install an extenstion first, but i can't find one at 
http://www.call-with-current-continuation.org/eggs/!
