From the developer:
The BNBuild Syntax Compiler translates syntax descriptions contained in .TXT and .RTF files into the binary syntax format of SMSC’s tools (.PBN files), which then can be loaded into OptoLyzer Standard Plus, OptoLyzer Professional, and OptoLyzer Suite. BNBuild can also merge several binary syntax files to one syntax tree. The merged or imported binary syntax files can be translated back to the syntax description for further editing.
