Description

Something like:

gflags::define! {
    -f, --file <PATH>...
}

where it would accept the same flag multiple times (-f path1 -f path2 -f path3) and expose them all in a vec or slice to the application.

Contributor guide

Research direction
Examine the existing `define!` macro implementation and the flag parsing logic to add support for collecting multiple values into a vector.
