Anil,
  It contains the AT&T (actually USL or Unix Systems Laboratories) class
libraries which are shipped with the USL C++ Language System 3.0 (aka
Cfront 3.0).  The libraries are (1) Iostreams
                                (2) Complex Numbers
                                (3) Tasks
If you are porting C++ applications from a Unix system, then (1) and (3)
may be of interest to you.  (1) is a type-safe replacement to the ANSI-C
printf, scanf, etc. family of functions, and it illustrates (both good
and bad) the effects of multiple inheritance. (2) is useful for Sci/Math
programmers only, and the class library is a "text-book" example of
what can be done with OOP.  (3) is great on Unix systems, since Unix does
not have threads, just processes.  On OS/2, (3) is less useful than
using BeginThread/CreateThread etc. (3) is definitely for Unix porters.
  If you are doing stdio-type of programming, then (1) is also useful.
If you are doing PM programming, it is not.
