--- | Computation of @'handleStaticDir' dir@ maps all files in @dir@
--- and its subdirectories on the filesystem to the 'ResTree'. The
--- 'Resource' must be in the /Examining Request/ state before the
--- computation. It will be in the /Done/ state after the computation.
---
--- If you just want to place a static directory tree on the 'ResTree',
--- you had better use 'staticDir' rather than this.
