The getopt is to be used for user not to stay in the script but launch it each
time he needs to do something; it is more useful then menu because 0) if one
runs your script with a typo (in plugin name, for example), it is more easily
corrected in shell command-line then; 1) I prefer Z line editor to any input
editing read provides; 2) it makes your script able to be used in users'
scripts. If you make scripts list stay in /tmp after script exits and make a
code that will ignore it if it is 1 hour old, then this will be possible.

Perl - yes. «No HTML regex parsing» - no: HTML should not be parsed with regex
because it is not a regular language and thus every regex parser is very prone
to errors, especially when something changes even slightly.
By the way, why you message contains lots of {plus}AD4, {plus}ALs and other
{plus}A{something}? It is not very easy to find you reply with these.
