Remain backward compatible but use ucl for the pkg-messages, which allows to:
- append messages one after the other
- only print message on delete, install, upgrade from a version to another
If pkg-message starts with a [ we consider it should be a valid ucl file
The format is the following:
[
{ message: "Always print" },
{ message: "package being removed", type: remove },
{ message: "package being installed", type: install },
{ message: "package is being upgraded", type: upgrade },
{ message: "Upgrading from lower than 1.0", maximum_version: "1.0", type: upgrade },
{ message: "Upgrading from higher than 1.0", minimum_version: "1.0", type: upgrade },
{ message: "Upgrading from >1.0 < 3.0", maximum_version: "3.0", minimum_version: "1.0",
]
Because it is ucl one can use some sugar like:
[
{ message = <<EOD
formatted
message 'with fancy things'
EOD
},
}

Backtick command substitution `STATEMENT` is legacy syntax with several
issues.
- It has a series of undefined behaviors related to quoting in POSIX.
- It imposes a custom escaping mode with surprising results.
- It's exceptionally hard to nest.
$(STATEMENT) command substitution has none of these problems, and is
therefore strongly encouraged.
