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:
    --num-threads=N                 number of threads to use [1]
    --max-requests=N                limit for total number of requests [10000]
    --max-time=N                    limit for total execution time in seconds [0]
    --forced-shutdown=STRING        number of seconds to wait after --max-time before forcing shutdown, or 'off' to disable [off]
    --thread-stack-size=SIZE        size of stack per thread [64K]
    --tx-rate=N                     target transaction rate (tps) [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
  
  Pseudo-Random Numbers Generator options:
    --rand-type=STRING random numbers distribution {uniform,gaussian,special,pareto} [special]
    --rand-spec-iter=N number of iterations used for numbers generation [12]
    --rand-spec-pct=N  percentage of values to be treated as 'special' (for special distribution) [1]
    --rand-spec-res=N  percentage of 'special' values to use (for special distribution) [75]
    --rand-seed=N      seed for random number generator. When 0, the current time is used as a RNG seed. [0]
    --rand-pareto-h=N  parameter h for pareto distibution [0.2]
  
  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)
    --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.
