libast - introduction to the ast library
This section describes the AST (AT&T Software Technology) library functions of the libast library. libast serves three major purposes. First, it presents (a subset of) POSIX/ANSI standard headers and interfaces on non-compliant systems. Second, it provides a portable base of routines that implement concepts common to all UNIX system variants. Finally, it is a forum for modern implementations of features present (or lacking) in the standard C libraries. Features better provided by separate libraries are omitted from libast. For example, most terminal driver interface issues are left for special purpose libraries such as curses(3).
The libast related header files are installed in the directories

The library documentation is still under construction. Yes, some of it has been in this state for 20 years. Thank goodness our commands self-document.
