A quick rundown: - added `file::{readdir, stat, mkdir, rmdir}` - Added access-constrained versions of `FileStream`; `FileReader` and `FileWriter` respectively - big rework in `uv::file` .. most actions are by-val-self methods on `FsRequest`; `FileDescriptor` has gone the way of the dinosaurs - playing nice w/ homing IO (I just copied ecr's work, hehe), etc - added `FileInfo` trait, with an impl for `Path` - wrapper for file-specific actions, with the file path always implied by self's value - has the means to create `FileReader` & `FileWriter` (this isn't exposed in the top-level free function API) - has "safe" wrappers for `stat()` that won't throw in the event of non-existence/error (in this case, I mean `is_file` and `exists`) - actions should fail if done on non-regular-files, as appropriate - added `DirectoryInfo` trait, with an impl for `Path` - pretty much ditto above, but for directories - added `readdir` (!!) to iterate over entries in a dir as a `~[Path]` (this was *brutal* to get working) ...<del>and lots of other stuff</del>not really. Do your worst!
