DESCRIPTION

This script is a command-line interface for Bench.

% bench prog.pl

is roughly equivalent to:

% perl -MBench -e'do "/abs/path/to/prog.pl"'; # time the whole program

while:

% bench -e 'some_code()'
% bench 'some_code()'

is roughly equivalent to:

% perl -MBench -e'bench sub { some_code() }'

FAQ

Why use this instead of 'time prog.pl'?

The script is more portable (should run under Windows too).

Why use this instead of 'perl -MBench -e'bench sub { ... }'?

bench '...' is shorter to type.

TODO

• -I?
