I'm not sure if Perl supports error handling in the same manner (try and catch, or similar), but I'm sure somebody here can clue me in.

darobin mentions this below - use eval BLOCK with die to catch and throw exceptions: 

eval {
   # code that might die
};

if ($@) {
   # $@ contains your exception
}

Update: merlyn is right, of course - forgot the ";". Curse my flying fingers! :-)

    Don't forget the semicolon after the eval {}. That kind of eval is an expression, not a statement, so it needs a semicolon to become a statement.
