PROGRAM:
NAME
spark - examines SPARK programs and generates verification conditions
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.
