You say `make', and a TTF compiler and decompiler together with an
annotated documentation (in HTML format) gets built. You need Java
and its development package (for `javac') for building and running the
compiler stuff; it should work out of the box.

Yes. Adobe provides the document as-is; it is mainly intended as a
guide to developers who are trying to parse or build OpenType data.

Definitely not.

Uh, oh, please give an example that demonstrates your concerns.
