/* Overall Structure */
/* ================= */
/* -------------------------------------------------------------------------------------------- */
/* This header contains a complete set of types and macros for dealing with the PEF executable */
/* format. While some description is provided, this header is not meant as a primary source */
/* of documentation on PEF. An excellent specification of PEF can be found in the Macintosh */
/* Runtime Architectures book. This header is primarily a physical format description. Thus */
/* it depends on as few other headers as possible and structure fields have obvious sizes. */
/* */
/* The physical storage for a PEF executable is known as a "container". This refers to just */
/* the executable itself, not the file etc. E.g. if five DLLs are packaged in a single file's */
/* data fork, that one data fork has five containers within it. */
/* */
/* A PEF container consists of an overall header, followed by one or more section headers, */
/* followed by the section name table, followed by the contents for the sections. Some kinds */
/* of sections have specific internal representation. The "loader" section is the most common */
/* of these special sections. It contains information on the exports, imports, and runtime */
/* relocations required to prepare the executable. PEF containers are self contained, all */
/* portions are located via relative offsets. */
