This package provides Concrete Roman fonts, designed by Donald Knuth, originally for use with Euler mathematics fonts. Alternative mathematics fonts, based on the concrete parameter set are available as the concmath fonts bundle. LaTeX support is offered by the beton, concmath and ccfonts packages. T1- and TS1-encoded versions of the fonts are available in the ecc bundle, and Adobe Type 1 versions of the ecc fonts are part of the cm-super bundle.
