I am having the following directory-structure:

```
├── build.lua
└── CharisSIL-Regular.ttf
```

With the following `build.lua`:

```lua
module              = "bar"
tdslocations        = {
  "fonts/truetype/" .. module .. "/" .. "*.ttf"
}
sourcefiles         = { "*.ttf" }
installfiles        = sourcefiles
```

the font gets installed at the correct location, but my intended directory structure is this:

```
├── build.lua
└── support
    └── CharisSIL-Regular.ttf
```

I tried the following `build.lua` without success:

```lua
module              = "bar"
tdslocations        = {
  "fonts/truetype/" .. module .. "/" .. "*.ttf"
}
sourcefiles         = { "support/*.ttf" }
installfiles        = sourcefiles
```

What's wrong here? I don't want to clutter my working directory with files other than dtx, ins and lua, but I want this font to be installed.
