ImpPath
Simple C++ library for path manipulation
... file systems, and thus doesn't know anything about symbolic links.
Primarily designed for usage in a secure environment with known simple limitations. For example, for working with internal application resource paths referencing a "sandboxed" virtual filesystem (like with PhysicsFS). Platform-specific path support is mainly intended for tools (e.g. map editor) which need to share a common code base (and perhaps some hard-coded resources) with the main sandboxed application (e.g. game).
