How to write system-specific, static checkers in metal

This paper gives an overview of the metal language, which we have designed to make it easy to construct system-specific, static analyses. We call these analyses extensions because they act as the input to a generic analysis engine that runs the static analysis over a given source base. We also interchangeably refer to them as checkers because they check that a user-specified property holds in the source base and report any violations of that property. Note that checkers may not detect all violations of a specified property. Their goal is to find as many violations as possible with a minimum of false positives
