da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chinThe advanced software technology department has been collecting useful C
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chinroutines in a single library called libast. libast is used by nmake, the
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chinnmake cpp (which is mainly based on another library (libpp)), CIA
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin(C information abstractor from Robin Chen), and a collection of other
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin/bin and /usr/bin commands that benefit from concentrating functionality
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chinMore detail is available in the man pages. libast contains:

da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin`nmake install' from this directory, otherwise use
