* Simplified, translated format of a symbol table entry:
*
* Note:
* Complete symbol table definitions reside in <stab.h> and simplified
* definitions in <nlist.h>. These sets of definitions are not fully
* compatible with each other; symbol table information as defined in
* <nlist.h> does not correspond directly to a.out file contents, but
* instead is obtained by translating such information with nlist(3).
* The <nlist.h> definitions do not provide access to all symbol table
* information, but are more convenient than the <stab.h> definitions
* for what they do cover.
*
* <Stab.h> and <nlist.h> are mutually incompatible;
* at most one may legally be included in a compilation.
*
* The n_type and n_value fields are not contained directly in
* an a.out file, but rather are pieced together by nlist(3) from
* addressing mode, link table, and module table information in
* the file.
