NAME
checker - SPARK Proof Checker SYNOPSIS
checker [OPTIONS] [FILE] DESCRIPTION
The SPARK Proof Checker can be used to discharge verification conditions produced by the Examiner (*.vcg), possibly simplified by the Sim- plifier (*.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 writ- ten into a plg file. OPTIONS
A summary of options is included below. All options may be abbreviated to the shortest unique prefix. -help Show summary of options. -version Display version information. -plain Adopt a plain output style (e.g. no dates or version numbers). -overwrite_warning Confirmation needed to overwrite command or proof log files. -command_log=LOG_FILE Specify file name for the command log file. -proof_log=PLG_FILE Specify file name for the proof log file. -execute=LOG_FILE Execute a previously generated command log file. -resume Resume a previously saved session.
