I’m building a new tool and my focus should be on the new problem the tool is going to solve. The basic problems a developer faces I want to solve with known solutions/frameworks. These are my choises:

• Antlrworks + Antlr: generate a parser to validate and parse the input
• ActiveRecord: build on top of nHibernate to manage my data
• Sqlite: lightweight database, not realy a framework, but a solution for my problem
• ExcelLibrary: read and write to MS Excel, without MS Excel, more a util

Now my focus can be on the real tool: an EVT tool.
