-//! \brief A file reader backed by a standard input/output `FILE*`.
-//!
-//! This class accepts an already-open `FILE*`. It is not responsible for
-//! opening or closing this `FILE*`. Users of this class must ensure that the
-//! `FILE*` is closed appropriately elsewhere. Objects of this class may be used
-//! to read from `FILE*` objects not associated with filesystem-based files,
-//! although special attention should be paid to the Seek() method, which may
-//! not function on `FILE*` objects that do not refer to disk-based files.
-//!
-//! This class is expected to be used when other code is responsible for
-//! opening `FILE*` objects and already provides `FILE*` objects. A good use
-//! would be a WeakStdioFileReader for `stdin`.
