Section 37:
[37.6] What is the NIHCL? Where can I get it?

NIHCL stands for "National-Institute-of-Health's-class-library." It can be acquired via 128.231.128.7/pub/NIHCL/nihcl-3.0.tar.Z

NIHCL (some people pronounce it "N-I-H-C-L," others pronounce it like "nickel") is a C++ translation of the Smalltalk class library. There are some ways where NIHCL's use of dynamic typing helps (e.g., persistent objects). There are also places where its use of dynamic typing creates tension with the static typing of the C++ language.
