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).

On the other hand, bench can only time Perl scripts.

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

bench '...' is shorter to type.

TODO

• Accept -I?
