Dividend Data Toolkit

Dividend Data Toolkit is a dependency-free Python command-line toolkit for auditing dated dividend payment records and calculating one company's indirect exposure across ETF positions. It validates date windows, payment inputs and explicit split bases, and reports assumptions and missing-coverage warnings rather than forecasting returns. This SourceForge code-only release contains MIT-licensed original code and documentation plus clearly fictional sample CSV files for repeatable tests. It does not relicense or include issuer data from the canonical GitHub repository, provide live market quotes, or give investment advice.
