+//! \brief A `PLOG()` macro usable for standard input/output error conditions.
+//!
+//! The `PLOG()` macro uses `errno` on POSIX and is appropriate to report
+//! errors from standard input/output functions. On Windows, `PLOG()` uses
+//! `GetLastError()`, and cannot be used to report errors from standard
+//! input/output functions. This macro uses `PLOG()` when appropriate for
+//! standard I/O functions, and `LOG()` otherwise.
