commit 908bee3d4c521ccbfbd8cc21d6a843e084e73677
Author: Tatsuhiko Miyagawa <miyag...@bulknews.net>
Date:   Tue Jun 28 13:51:23 2011 -0400

    Allow -Ilib to exec
    
    Because of how PERL5OPT and -I/-M works, we can't reliably make
    `carton exec -- perl -Ilib foo.pl` nor even `-Mlib=lib` load library
    from lib. We allow `-Ilib` to be passed to the exec's option, so that:
    
        carton exec -Ilib -- perl script.pl
    
     would load modules from lib/, and makes the development easier.
    
    See lib::core::only/CAVEATS for details.
