+
+# bounceback
+
+An `io.ReadSeeker` and `io.WriteSeeker` that returns to the right place before
+reading or writing. Useful when the same file resource is being reused for reads
+or writes throughout that file.
+
+# list_files
+
+A recursive path walker that supports filters.
+
+# seekable_buffer
+
+A memory structure that satisfies `io.ReadWriteSeeker`.
+
+# copy_bytes_between_positions
+
+Given an `io.ReadWriteSeeker`, copy N bytes from one position to an earlier
+position.
+
+# read_counter, write_counter
+
+Wrap `io.Reader` and `io.Writer` structs in order to report how many bytes were
+transferred.
+
+# readseekwritecloser
+
+Provides the ReadWriteSeekCloser interface that combines a RWS and a Closer.
+Also provides a no-op wrapper to augment a plain RWS with a closer.
+
+# boundedreadwriteseek
+
+Wraps a ReadWriteSeeker such that no seeks can be at an offset less than a
+specific-offset.
+
+# calculateseek
+
+Provides a reusable function with which to calculate seek offsets.
+
+# progress_wrapper
+
+Provides `io.Reader` and `io.Writer` wrappers that also trigger callbacks after
+each call. The reader wrapper also invokes the callback upon EOF.
+
+# does_exist
+
+Check whether a file/directory exists using a file-path.
+
+# graceful_copy
+
+Do a copy but correctly handle short-writes and reads that might return a non-
+zero read count *and* EOF.
+
+# readseeker_to_readerat
+
+A wrapper that allows an `io.ReadSeeker` to be used as a `io.ReaderAt`.
+
+# simplefileinfo
+
+An implementation of `os.FileInfo` to support testing.
