Maintenance Dilemmas

     90         s/$/;/g if (/apply/);

     apply "grp1_load" 0 =;

What is line 90 for?
1. It might be superfluous
2. It might be there because not all inputs will have ; on the apply lines
3. It might be there Just In Case
I'm going to take a middle way:
- Assume that the ; will always be there
- But raise a fatal error if it is missing

        die "Missing ';' in 'apply' line" if /apply[^;]*\n/;
