#
# Check C++ Toolkit in all previously built configurations
# (see 'cfgs.log', generated with 'build.sh' script).
#
# USAGE:
#     check.sh {run | concat | concat_err | concat_cfg | load_to_db}
#
# Use 'run' command first, than use other commands.
# For 'concat_cfg' -- use 'run', 'concat' and 'concat_err' commands first.



########### Arguments

script="$0"
method="$1"

# Maximum number of parallel running test configurations
max_tasks=2
# Sleep timeout between checks on finished 'run' tasks (seconds)
