//! The main points of the manual modifications are as follows:
//! * Removed `hdr` from each command struct so that we can read the header and a command body separately.
//!   (cf. [related discussion](https://markmail.org/message/tr5g6axqq2zzq64y))
//! * Added implementations of DataInit for each struct.
