Concrete Text fonts have been designed by Donald Knuth for his Concrete
Mathematics book; matching Math fonts have been designed by Ulrik Vieth.
While the Knuth's Computer Modern family has been widely accepted in
scientific publishing, his newer Concrete design has not been very
commonly used---since until now scalable versions of the Concrete fonts
simply had not been available. They are now!
Just like the Computer Modern family, the Concrete fonts include
multiple design sizes. The existing macro support for the Concrete fonts
(the concrete, concmath, and beton styles) makes the MicroPress Concrete
fonts immediately useful for most TeX systems.
Concrete fonts are darker than the Computer Modern fonts and usually
much more legible in online documentation (Pdf). MicroPress uses
Concrete fonts to typeset most of its program documentation.
First released in November 1999.
