NAME
    Bencher::Scenario::RandomLineModules - Benchmark modules which pick
    random line(s) from a file
VERSION
    This document describes version 0.05 of
    Bencher::Scenario::RandomLineModules (from Perl distribution
    Bencher-Scenario-RandomLineModules), released on 2017-07-10.
SYNOPSIS
    To run benchmark with default option:
     % bencher -m RandomLineModules
    To run module startup overhead benchmark:
     % bencher --module-startup -m RandomLineModules
    For more options (dump scenario, list/include/exclude/add participants,
    list/include/exclude/add datasets, etc), see bencher or run "bencher
    --help".
DESCRIPTION
    Packaging a benchmark script as a Bencher scenario makes it convenient
    to include/exclude/add participants/datasets (either via CLI or Perl
    code), send the result to a central repository, among others . See
    Bencher and bencher (CLI) for more details.
BENCHMARKED MODULES
    Version numbers shown below are the versions used when running the
    sample benchmark.
    File::Random::Pick 0.02
    File::RandomLine 0.20
BENCHMARK PARTICIPANTS
    *   File::Random::Pick::random_line (perl_code)
        Function call template:
         File::Random::Pick::random_line(<filename>)
    *   File::RandomLine (perl_code)
        Code template:
         my $rl = File::RandomLine->new(<filename>); $rl->next
BENCHMARK DATASETS
    *   1k_line
    *   10k_line
