checker [OPTIONS] [FILE]

The SPARK Proof Checker can be used to discharge verification conditions produced by the Examiner (*.vcg), possibly simplified by the Simplifier (*.siv). This command is usually used when verification conditions cannot be discharged automatically by the Simplifier.

By default checker runs in interactive mode. It accepts commands from user and writes them into a cmd file (or other file specified by -command_log option). This file can be used later to run checker in batch mode (using option -execute). Additionally, proof log is written into a plg file.

A summary of options is included below. All options may be abbreviated to the shortest unique prefix.
