This directory contains the sources and binary versions for Scilab.
The information here concerns the modifications in Scilab 2.1.1.
This release is not a major release.

2. Installation
---------------

	a- You have the source and binary of Scilab 2.1 already.
        --------------------------------------------------------
	Get the file scilab-2.1-2.1.1.diff; keep the compiled version
	of Scilab 2.1 and apply the patch (the patch-file is 
	scilab-2.1-2.1.1.diff; it contains information on how to
	proceed.

	Doing the patch creates a .orig for each modified file.	You 
	should kill the .orig files in the man in order to get the
	new info for the help:
		kill man*/*.orig  (AFTER making the patch)


	b- You are installing Scilab for the first time or you just
		have an old binary distribution 
        -----------------------------------------------------------
	Get the file scilab-2.1.1.tar.gz or scilab-2.1.1.tar.Z and
	follow the instructions inside for the source version. And,
	for binary version corresponding to your system (say XXX), 
	get the file scilab-2.1-XXX.tar.Z or scilab-2.1-XXX.tar.gz,
	and proceed similarly. See README-2.1.1 for more details.
	


3. Summary of changes 
---------------------

   This is the third release of Scilab.  In addition to dozens of
bug fixes, a major improvement in X-interface has resulted in a
more efficient interpretation; Scilab is not only faster, it uses
less CPU time.  Here is a list of the most significant changes:


1- Improvements in dynamic (incremental) link capability:
a number of problems related to dynamic (incremental) link have
been fixed. Now, incremental link works on all platforms if
Scilab is built from source (on IBM RS6000 still only one routine 
can be linked at a time). 

2- It was noted by a number of users that high demand was placed on 
the processor when running Scilab, even when the program was idle or 
iconised. This problem has now been fixed. The solution has been 
proposed by Nick Bailey (Leeds University).
This problem was due to a bad choice for a parameter in the select
routine. Another event handling improvement has also been incorporated.

3- A number of minor corrections have been done in the on-line manual.

4- On the HP and IBM RS6000 platforms, a major bug in the "file 
operations" menu has been fixed. A function loaded with getfc 
containing a syntax error was not properly closed and thus became 
inaccessible for future getfc's.

5- Improvement in postcript generation of figures and xfig compatibility.
Improved epsf compliance and format of xfig file is now FORMAT3.0.
(xs2fig generating Protocol 3.0 xfig Format 
PLEASE UODATEE if necessary your xfig version accordingly).

6- Bug concerning the help on SGI has been fixed in binary releases.
