Hello.
>AAA_xxx_yyy = "true"
Thank you, I will try. I could not figure out but I feel it should work.

This should work for "and":
AAA_xxx_yyy = "true"
(There was a time many releases ago where this didn't, but it should work in
any release in the last few years).
For "or" you already have the answer above, basically do it with the same
value for both overrides:
AAA = "false"
AAA_xxx = "true"
AAA_yyy = "true"

Same thing - for and:
do_install_append_xxx_yyy() {
}
for or:
do_install_append_xxx() {
}
do_install_append_yyy() {
}
Note, we're appending here rather than setting as above, but otherwise setting
a function is pretty much the same in terms of operations as a variable - the
syntax is slightly different and immediate operations (such as +=) aren't
allowed, but the same rules apply for overrides and deferred operations such
as _append.
Cheers,
Paul
