Packageinfo for dlangs dub packages

Sooner or later the question of licenses of dependencies comes up. This package helps keeping an overview. See forum.dlang.org/Learn for discussion of this.

Basic Usage

Please add the following to your artifact (after dub fetch packageinfo).

preGenerateCommands "$DUB run packageinfo"
sourcePaths "source" "out/generated/packageinfo"
importPaths "source" "out/generated/packageinfo"

This will create a module in out/generated/packageinfo/packageinfo.d that contains all dependencies with selected informatiosn (name, version and license).

The information is provided as an enum, so it is possible to access it at compile time

import packageinfo;
static foreach (p; packageinfo.packages)
{
    pragma(msg, p);
}

or runtime

import std.stdio : writeln;
import packageinfo;
writeln(packageinfo.packages);

Program arguments

To select one configuration of your dub project, pass --config=CONFIGNAME to packageinfo. See the dogfood configuration in packageinfo itself as an example.
