SYNOPSIS

spark [OPTIONS] [ FILE_LIST or @METAFILE ]

DESCRIPTION

The Examiner for SPARK, spark, analyses the given source files for errors and violations of the SPARK subset and (optionally) generates verification conditions and dead path conjectures necessary for proof of absence of run-time exceptions and partial correctness.

This manual page only summarises the spark command-line flags, please refer to the full Examiner manual for further information.

OPTIONS

These options do not quite follow the usual GNU command line syntax. All options start with a single dash instead of the usual two and they can also be abbreviated, as long as the abbreviation is unique. For example -help can be abbreviated to -he but not -h as this clashes with -html.
