Noweb is a documentation and code writing tool built up onto a working scheme of chunks, where each chunk is a piece of reusable code. Documentation, on the other hand, can be done in Latex or HTML, in place together with chunks. Hence, out of a nw file one can both achieve a source [say, .c] file and a documentation [say, .html] file. In the terminology of literate programming, obtaining these files are called tangling and weaving, respectively.

The original noweb is a collection of command line tools; mainly consisting notangle and noweave. NwControl wraps a UI around these binaries to establish a specialized-for-OS-X workspace.
