1. Introduction
----------------

Ns-allinone is a package which contains required components and some of
optional components used in running ns. The package contains an
"install" script to automatically configure, compile and install these
components. If you haven't installed ns before and want to quickly try
ns out, ns-allinone may be easier than getting all the pieces by hand.
 
Currently the package contains:
  
- Tcl       Tcl release 8.0.4     (required component)
- Tk        Tk release 8.0.4      (required component)
- Otcl      otcl release 1.0a5    (required component)
- TclCL     tclcl release 1.0b9   (required component)
- Ns        ns release 2.1b6      (required component)
- TclDebug  tcl-debug relase 1.9  (optional component)
- Nam       Nam release 1.0a8     (optional component)
- Xgraph    xgraph version 12     (optional component)
- GT-ITM    GT Internetwork
            Topology Model        (optional component)
- SGB       Stanford GraphBase
            package               (optional component)
- CWEB      CWeb version 1.0 (?)  (optional component)
- ZLib      zlib version 1.1.3    (optional component) 

2. FEATURES IN ns-allinone?
---------------------------

Features in this version include:
 
- Self-contained:  All installation will be kept in a directory to help
		   the user manange and use the package. The execution of ns
		   ns or nam does not need any ther support outside
		   this directory

- Bugs fixed:      All components inside the package, with the
                   exceptoin of Tcl/Tk, are the most recent versions;
                   TclDebug does not work with the recent versions of
                   Tcl/Tk.

- Easy to Install: Only one-line command is needed to build all ns
		   components


2. Installing the package
--------------------------

All you need to do is type "./install" under this directory. The install
script will compile and install the whole package for you. The script also
will tell you the final installation result.

2.1. Known problems
---------------------
- Apply geog.patch to gt-itm/src/geog.c if you experience compilation
  problems.  

- Apply tclPosixStr.patch to tcl8.0.4/generic/tclPosixStr.c under
  RedHat Linux. 

- Without --enable-gcc explicitly in the configure command line, ns will
  not compile on some SPARC and HPUX platforms.

The allinone package should install without error on most versions of
Unix.  If you have problems, see:
