The D language is a specification for a high level programming language. The D Framework is the compilers, debuggers, IDE's, and 
command line tools, libraries, or lack there of, which help with writing, building, debugging, and maintaining programs written 
in the D language.

IMHO, the D language is a beautiful thing, however the D framework is very much lacking as compared to Java, .NET, even C++.
