Version history

GNU BPEL2oWFN has been developed for quite some time now. See the ChangeLog for details or try out the older versions.


GNU BPEL2oWFN is open source software, licensed under the AGPL3+.



Installing and running GNU BPEL2oWFN requires a bunch of other tools:

Running requires:
Compiling requires:
  • GCC - The GCC compiler
Testing requires:
  • Autotools test suite - Part of the GNU Auto-Tools for automated Tests
  • LCOV - LCOV is a graphical front-end for GCC's coverage testing tool gcov. It collects gcov data for multiple source files and creates HTML pages containing the source code annotated with coverage information.
Contributing requires:
  • Kimwitu++ - The Term processor - Kimwitu++ is a tool for processing trees (i.e. terms). It is a meta tool: Kimwitu++ can be used for generating software - especially when building compilers.
  • Bison - Gnu parser generator - Bison is a general-purpose parser generator that converts an annotated context-free grammar into a deterministic LR or generalized LR (GLR) parser employing LALR(1) parser tables.
  • GNU Gengetopt - Gengetopt generates a C function that uses getopt_long function to parse the command line options, to validate them and fills a struct .
  • flex: The Fast Lexical Analyzer - Flex is a tool for generating scanners. A scanner, sometimes called a tokenizer, is a program which recognizes lexical patterns in text. The flex program reads user-specified input files, or its standard input if no file names are given, for a description of a scanner to generate.
