README file for the standard subdirectory

________________________________________________________________________

The standard directory contains a completely portable implementation of
the cslib library for use with the textbook "The Art and Science of C: A
Library-Based Approach" (Addison-Wesley, 1995).

The graphics library provided in this directory is a machine-independent
implementation that writes a data file called graphics.ps that can then
be sent to a PostScript printer.  If you want to draw actual figures on
the screen, you need a version of graphics.c that has been tailored for
use with your specific system.  Several implementations of graphics.c
are included in other subdirectories (unix-xwindows, mac-think-c, and
pc-borland) of the cslib directory.

INSTALLING THE STANDARD LIBRARIES

First of all, make sure that the standard version of the libraries is
the one you want to install.  If you are running on one of the platforms
for which the full cslib library package is implemented (XWindows on
Unix, Borland C/C++ on the IBM PC, or THINK C or Symantec C++ on the
Macintosh), you should be installing the version that was designed for
that system.  The cslib library produced by those packages is not only
more powerful but also easier to install.

The steps required to install the standard library package depend very
much on what type of computer system and C compiler you have.  If you
are running on a Unix system, you should adopt the following procedure:

TO INSTALL THE STANDARD VERSION OF THE LIBRARIES ON A UNIX SYSTEM:

1.  Use FTP to retrieve the file standard.shar to the home directory on
    your machine.

2.  Execute the standard.shar script by typing

         sh standard.shar

    This step creates a top-level directory called cslib that contains
    all of the relevant files.

3.  Connect to the cslib directory.

4.  Rebuild the object files and libraries by typing

         make

5.  Copy the file gccx from the cslib directory into a directory on your
    command search path.  If you will be the only person using the
    libraries, you could put this file in your private command
    directory, which is usually ~/bin.  If you are installing this
    command for use by any user on the system, you will need to put it
    in a public directory, such as /usr/local/bin.  For public
    installation to work, your cslib directory must be readable by other
    users.

If you are not using a Unix system, you should instead adopt the
following more general approach, filling in details as appropriate for
your own hardware and software platform:

1.  Use FTP to copy all of the files in the standard directory to a new
    working directory on your machine.

2.  Copy the .h files from this directory into the standard #include
    path used by your compiler.

3.  Compile each of the source files (exception.c, genlib.c, graphics.c,
    random.c, simpio.c, and strlib.c) to produce the corresponding
    object file.

4.  Combine the object files together to produce a library file.  The
    steps required to do so vary substantially from system to system.

5.  If you are installing this package on a shared machine, copy the
    library into some public directory where students can easily gain
    access to it.

NOTES AND DISCLAIMERS

The cslib libraries are in the public domain and may be freely copied
and distributed, although they remain under development.  No warranties
are made concerning their correctness or stability, and no user support
is guaranteed.  Bug reports and suggestions, however, are appreciated
and may be sent to
