'p4 label -i' expects to read the label spec from stdin.  The quickest 
way to generate a valid label spec is with 'p4 label -o labelname'.  Try 
it to see the format.  That won't actually create the a label called 
'labelname' if it doesn't already exist, it just prints out  a valid 
spec.  Pipe the output to 'p4 label -i', however, and your label will be 
created.  You can use '-t template' as an additional argument to 'p4 
label -o' if you want the view restricted to some subset of your depot 
as specified in an existing label.

This part should be fine.
