You don't want to make other people use the '--' switches to use the script?
Why not? Getopt::Long will probably accommodate you in this, but I would
suggest reserving the single '-' for one-letter options, and the double '-'
for long options. That way, the one-letter options can be bundled, e.g. -rh
for --reg_backup and --html.
Also, it might be more natural to use 'reg-backup', instead of 'reg_backup'.

This can be accomplished by specifying a subroutine reference as your value,
instead of a scalar reference. E.g.
GetOptions(
reg_backup => \®_backup,
html => \&html,
);
You mentioned in a previous message in this thread that reg_backup would
setup an array, and html would process it. This would have to be
accomplished by some shared variable; html() would have to verify the
variable was setup correctly, and if not, do something to notify the user.
See the "User-defined subroutines to handle options" section in perldoc
Getopt::Long. I would suggest you read the entire perldoc for the module at
least once, to get an idea of what it provides.

I don't completely understand what you're trying to describe here.
Hopefully the advice I've already given will give you enough of a starting
point to solve the problem yourself.
