 ## Purpose of Static Analysis Verification and Evaluation (SAVE) project
 Usage of [static analyzers](https://en.wikipedia.org/wiki/Static_program_analysis) - is a very important part of development each and every software product.
 All human beings can make a mistake in their code even when a software developer is writing all kinds of tests and has a very good test-coverage.
