This is simply to add configuration lines to the generated configuration
file. The reason why I didn't went for an attribute set is that the
taskdrc file format doesn't map very well on Nix attributes, for example
the following can be set in taskdrc:
server = somestring
server.key = anotherstring
In order to use a Nix attribute set for that, it would be way too
complicated, for example if we want to represent the mentioned example
we'd have to do something like this:
{ server._top = somestring;
server.key = anotherstring;
}
Of course, this would work as well but nothing is more simple than just
appending raw strings.
