+ * Log and return the manifest of files for the given game asset directory.
+ * The assets used to build the mapper are a filtered set of relevant files
+ * (map related assets) from the `Tribes2/GameData/base` folder. The manifest
+ * consists of the set of unique paths (case sensitive!) represented by the file
+ * tree AND the vl2 files as if they had been unzipped. Thus, each file in the
+ * manifest can have one or more "sources". If the file appears outside of a vl2,
+ * it will have a blank source (the empty string) first. Each vl2 containing the
+ * file will then be listed in order. To resolve an asset, the engine uses a
+ * layering approach where paths inside lexicographically-higher vl2 files win
+ * over the same path outside of a vl2 or in a lexicographically-lower vl2 file.
+ * So, to choose the same final asset as the engine, choose the last source in
+ * the list for any given path.
+ *
+ * Example:
+ *
+ * ```
+ * {
+ *   "textures/terrainTiles/green.png": ["textures.vl2"],
