Hello Folks,
I wonder if you can help me? its probably really easy but my head is not working. Assuming I have a : delimited file such as 
EQUIPMENT: BASEBALL: ACCESSORI
EQUIPMENT: BASEBALL: BALLS
EQUIPMENT: CYCLING
EQUIPMENT: GOLF: BAGS
EQUIPMENT: GOLF: BALLS
EQUIPMENT: OTHER BALL SPORTS:
EQUIPMENT: OTHER BALL SPORTS:
EQUIPMENT: RACQUET SPORTS: BAL
EQUIPMENT: RACQUET SPORTS: RAQ

I want to create a nice data structure such as
my %hash = ('EQUIPMENT' => {
                         'BASEBALL' => { 
                                        'ACCESSORI' => 1, 
                                          'BALLS' => 1,
                                         },
                         'CYCLING' => 1,
                         'GOLF' => { 'BAGS' => 1,
                                      'BALLS' => 1,
                                     },
                         'OTHER BALL SPORTS' => 1,
                         'RACQUET SPORTS' => { 'RAQ' => 1, 'BAL' => 1}
                        });

What would the algorithm be to convert it ? Reading in the file and splitting is done so I have an array for each line - but I cant think of how to create the array?
