[SGML Grammar tools. From: ftp-tei.uic.edu/pub/tei/grammar/README (about December 1995)] This directory (pub/tei/grammar) contains two subdirectories with material of interest for the study of SGML as a formal language or the implementation of SGML parsers. The subdirectory pub/tei/grammar/bison contains files with Bison grammars and Flex scanners for SGML document type definitions (p2bnf.y and p2bnflex.l), SGML document instances (p2doc.y and p2doclex.l), and SGML declarations (p2decl.y and p2declex.l). The grammars have been parsed with Bison to ensure that the grammars are clean, but the semantic actions do no useful work. More recent experience using these files as the basis for software that does perform useful work indicates that they are a helpful beginning, but that changes to the grammar may be needed now and then. The subdirectory pub/tei/grammar/iso8879 contains transcriptions of the full formal grammar of ISO 8879 (the SGML standard), either in numeric sequence of the productions in the standard (sgmlfull.syntax) or arranged in groups, so closely related productions are more readily found together, with dependency trees showing which productions depend on which others. In both the full and the topically arranged versions, references to other productions are augmented with production numbers (so instead of saying just 'name', a production will refer to '55 name'. -C.
