Skip everything between "Compiled-in database drivers:" and
"Compiled-in tests:" as that part depends on available database
drivers and thus, build options. Driver-specific options are tested
separately.

  $ sysbench --help | sed '/Compiled-in database drivers:/,/Compiled-in tests:/d' 
  Usage:
    sysbench [options]... [testname] [command]
  
  Commands implemented by most tests: prepare run cleanup help
  
  General options:
    --threads=N                     number of threads to use [1]
    --events=N                      limit for total number of events [0]
    --time=N                        limit for total execution time in seconds [10]
    --warmup-time=N                 execute events for this many seconds with statistics disabled before the actual benchmark run with statistics enabled [0]
    --forced-shutdown=STRING        number of seconds to wait after the --time limit before forcing shutdown, or 'off' to disable [off]
    --thread-stack-size=SIZE        size of stack per thread [64K]
    --thread-init-timeout=N         wait time in seconds for worker threads to initialize [30]
    --rate=N                        average transactions rate. 0 for unlimited rate [0]
    --report-interval=N             periodically report intermediate statistics with a specified interval in seconds. 0 disables intermediate reports [0]
    --report-checkpoints=[LIST,...] dump full statistics and reset all counters at specified points in time. The argument is a list of comma-separated values representing the amount of time in seconds elapsed from start of test when report checkpoint(s) must be performed. Report checkpoints are off by default. []
    --debug[=on|off]                print more debugging info [off]
    --validate[=on|off]             perform validation checks where possible [off]
    --help[=on|off]                 print help and exit [off]
    --version[=on|off]              print version and exit [off]
    --config-file=FILENAME          File containing command line options
    --luajit-cmd=STRING             perform LuaJIT control command. This option is equivalent to 'luajit -j'. See LuaJIT documentation for more information
  
  Pseudo-Random Numbers Generator options:
    --rand-type=STRING   random numbers distribution {uniform, gaussian, pareto, zipfian} to use by default [uniform]
    --rand-seed=N        seed for random number generator. When 0, the current time is used as an RNG seed. [0]
    --rand-pareto-h=N    shape parameter for the Pareto distribution [0.2]
    --rand-zipfian-exp=N shape parameter (exponent, theta) for the Zipfian distribution [0.8]
  
  Log options:
    --verbosity=N verbosity level {5 - debug, 0 - only critical messages} [3]
  
    --percentile=N       percentile to calculate in latency statistics (1-100). Use the special value of 0 to disable percentile calculations [95]
    --histogram[=on|off] print latency histogram in report [off]
  
  General database options:
  
    --db-driver=STRING  specifies database driver to use \('help' to get list of available drivers\)( \[mysql\])? (re)
    --db-ps-mode=STRING prepared statements usage mode {auto, disable} [auto]
    --db-debug[=on|off] print database-specific debug information [off]
  
  
    fileio - File I/O test
    cpu - CPU performance test
    memory - Memory functions speed test
    threads - Threads subsystem performance test
    mutex - Mutex performance test
  
  See 'sysbench <testname> help' for a list of options for each test.
