Hi monks,

Something of a novice question. Was looking through the source for some executable perl programs (cpan, module-starter, etc ...) and I noticed that they all start as follows:

#!/software/perl-5.8.8/bin/perl -w

eval 'exec /software/perl-5.8.8/bin/perl -w -S $0 ${1+"$@"}'
    if 0; # not running under some shell

[download]

My question is what exactly is going on there (especially here: $0 ${1+"$@"}) and how important is it?

Smoothie, smoothie, hundre prosent naturlig!
