The Use Case Editor is a tool used by business analysts and requirements engineers for capturing and organising functional and non-functional requirements. Specifically it captures and formally documents use cases using an automated document template, captures logical data models,  and automatically generates activity diagrams from use case primary and alternative path specifications. The tool is available for download by selecting the file UCEditorInstaller.msi from the download page. Documentation giving instructions on  its installation and use can be found here.

The GLR parsing suite PARSELR is a tool that generates and provides the runtime for generalised LR grammar parsers, as well as generating state machines from formal state machine descriptions. Similar in purpose to Bison or Yacc, this tool also incorporates the state-splitting algorithms used to extend it into a GLR parser. The tool takes an input grammar, and converts it into a C# source code parsing engine that is then incorporated into an application that needs a parser.

The parser can act as a compile-time tool generating fixed source code for a parser for a specific grammar. Alternatively it can operate dynamically, allowing the grammar rules to be specified or changed dynamically at run-time, with a new state machine parser being generated and launched as and when the grammar changes.

Note that the parser also incorporates the ability to call condition-testing functions at each shift or reduction. It is this that enables it to also implement complex finite state machines driven by grammar rules.

For more information on the parser suite and instructions on how to use it, see this link.
