WildCAD - a simple 2D drawing application

[Richard (Rikki) Andrew Cattermole]

dub isn't the issue, people who fight it like this, fight the D 
compilers and end up having issues.

You're fundamentally doing something that D compilers are not designed 
to handle. The problem is with -I flag. Being able to set a directory to 
look modules up in.

Problem is it needs to match the packages to directories.

I.e.

wildwidgets/lib/source/wcw/clipboard.d

Not:

wildwidgets/lib/source/clipboard.d

Also note: you should not use symlinks with VCS, there are 
cross-platform problems with it.
