SDF2 Bundle 2.3 requires:
   * ATerm Library 2.3.1

---++ News

This is mainly a maintenance release, fixing a number of
bugs. However, a number of important features have been added.

   * Fixed a bug in obtaining a parse table when restoring brackets
     with a grammar without start symbols.

   * Fixed implosion of alternative literals. ="-" | "+"= becomes
     =alt(1,[]) or alt(2,[])= because a literal does not have a
     representation in an imploded tree. This fixes a core dump

   * The efficiency of the syntax checker was improved
     drastically. This reduces parsetable generation times.

   * A new commandline tool: =filterPT=. It filters parse forests based
     on some command line arguments. Currently, we have one filter to
     find trees with a maximum or minumum number of occurrences of a
     certain non-terminal. It is used to implement filters for island
     grammars.

   * A new small package: tide-support. Contains a library for
     developing new TIDE debugging adapters.
