  Automatic software verification tools help to find hard-to-detect faults in
programs checked against specified requirements non-interactively. Besides,
they can prove program correctness formally under certain assumptions. These
capabilities are vital for verification of critical industrial programs like
operating system kernels and embedded software. However, such programs can
contain hundreds or thousands of KLOC that prevent obtaining valuable
verification results in any reasonable time when checking non-trivial
requirements. Also, existing tools do not provide widely adopted means for
environment modeling, specification of requirements, verification of many
versions and configurations of target programs, and expert assessment of
verification results. In this paper, we present the Klever software
verification framework, designed to reduce the effort of applying automatic
software verification tools to large and critical industrial C programs.
