OpenJade group's SGML parsing tools This package is a collection of SGML/XML tools called OpenSP. It is a fork from James Clark's SP suite. These tools are used to parse, validate, and normalize SGML and XML files. The central programs included in this package are 'onsgmls', which replaces sgmls, 'ospam', 'ospent', 'osgmlnorm', and 'osx'.
