to trigger/signal a rebuild for the transition 5.8.8 -> 5.10.0.
The list of packages is computed by finding all packages which end
up having either of PERL5_USE_PACKLIST, BUILDLINK_API_DEPENDS.perl,
or PERL5_PACKLIST defined in their make setup (tested via
"make show-vars VARNAMES=...").
By default, this module exports a single function: prompt(). It
prompts the user to enter some input, and returns an object that
represents the user input.
You may specify various flags to the function to affect its behaviour;
most notably, it defaults to automatically chomp the input, unless
the -line flag is specified.
