 Introduction</A>
 </H1>
 BlueGnu is a framework for testing other programs. It has been created
 to be compatible with DejaGnu. Its purpose is to provide a single
 front end for all tests. Beyond this, BlueGnu offers several
 advantages for testing:

 <P>
 <UL>
 <P>
 <LI>The flexibility and consistency of the BlueGnu framework makes it
 easy to write tests for any program, with the exception of GUI
 applications.

 <P>
 <LI>BlueGnu provides a layer of abstraction, which makes all tests
 (if correctly written) portable to any host or target where a program
 must be tested.

 <P>
 <LI>BlueGnu is written in [incr Tcl], which in turn is based on Tcl
 (Tool Command Language). The framework comprises two parts:
 <DL COMPACT>
 <DT>1.
 <DD>the testing framework,
 <DT>2.
 <DD>the test-suites or test-sets themselves.
 </DL>
 <P>
 <LI>BlueGnu will work with any Tcl based interpreter as long as
 [incr Tcl] has been included. You can include 'expect', 'Tk', and/or
 other extensions.

 <P>
 <LI>Includes DejaGnu release 1.6

 <P>
 </UL>
 <P>

 <H1><A NAME="SECTION00020000000000000000">
 Requirements</A>
 </H1>
 The following modules should have been installed, before you can
 install and/or use BlueGnu:

 <P>
 <UL>
 <LI>Tcl release 8.0 or higher,
 <LI>incr Tcl release 3.0 or higher.
 </UL>
 <P>
 Any other extensions that is compatible with Tcl release 8.0 can be used
 as well.

 <P>

 <H1><A NAME="SECTION00030000000000000000">
 Structure and Contents of the Release</A>
 </H1>

 <P>
 The root directory of the release contains the README files with
 installation instructions and the files needed to build and install
 this product. It also contains the executable scripts of the
 BlueGnu testing framework.

 <P>
 The top-level directories are listed below:

 <P>

 <H1><A NAME="SECTION00040000000000000000">
 Installation and use under Unix</A>
 </H1>

 <P>
 Before you can install and use BlueGnu you need to have installed the
 following three packages:
 <UL>
 <LI>Tcl version 8.0.3
 <LI>Tk version 8.0.3
 <LI>incr Tcl version 3.0.1
 </UL>The source for these packages should all be located in one directory.
 The subdirectory in the directory should be:
 <UL>
 <LI>tcl8.0.3
 <LI>tk8.0.3
 <LI>itcl3.0.1
 </UL>
 <P>
 The following examples use the command `./configure
 -prefix=/tools/...`. This will install all packages in a directory
 ``/tools''. When you omit the ``-prefix''-switch then the
 installation default will be the directory ``/usr/local''.

 <P>

 <H2><A NAME="SECTION00041000000000000000">
 Installation of needed Packages</A>
 </H2>

 <P>
 When you have not installed Tcl and the other needed extensions, then
 you need to retrieve the sources from ``www.tcltk.com/itcl''. You need
 to `gunzip` the files and do a `tar xf` of all these packages in one
 directory, let's call this directory ``TclTk''.

 <P>
 From the directory ``TclTk'', you should do the following to install
 the packages:

 <P>
 <PRE>
 % cd tcl8.0.3/unix
 % ./configure --prefix=/tools/tcl8.0.3 --enable-gcc --enable-shared
 % make
 % mkdir /tools/tcl8.0.3
 % make install
 % cd ../../tk8.0.3/unix
 % ./configure --prefix=/tools/tk8.0.3 --enable-gcc --enable-shared
 % make
 % mkdir /tools/tk8.0.3
 % make install
 % cd ../../itcl3.0.1
 % ./configure --prefix=/tools/itcl3.0.1 --enable-gcc --enable-shared
 % make
 % mkdir /tools/itcl3.0.1
 % make install
 </PRE>
 <P>

 <H2><A NAME="SECTION00042000000000000000">
 Installing BlueGnu</A>
 </H2>
 You can now `gunzip` and `tar xf` the BlueGnu version 2.0.3 in the
 directory ``TckTk''. This will create the directory
 ``bluegnu2.0.3''. Now do the following:

 <P>
 <PRE>
 % cd bluegnu2.0.3
 % ./configure --prefix=/tools/bluegnu2.0.3
 % make
 % mkdir /tools/bluegnu2.0.3
 % make install
 </PRE>
 <P>
 This will install BlueGnu in the directories:
 <UL>
 <LI>/tools/bluegnu2.0.3/bin
 <LI>/tools/bluegnu2.0.3/lib/bluegnu
 <LI>/tools/bluegnu2.0.3/info
 <LI>/tools/bluegnu2.0.3/man
 </UL>
 <P>

 <H2><A NAME="SECTION00043000000000000000">
 Using BlueGnu</A>
 </H2>
 When you have installed [incr Tcl] and BlueGnu and you have the
 respective ``bin'' directories in your PATH variable, then you can
 start running some tests. You can go into the BlueGnu source directory
 ``bluegnu2.0.3/testsets/examples'' and run the following:

 <P>
 <PRE>
 % bluegnu versionTcl.itcl
 % bluegnu ts_001
 % bluegnu ts_002
 % bluegnu ts_003
 </PRE>
 <P>
 The above test result should all be PASS. The following test will give
 a result UNKNOWN, because no pass/fail instruction have been given.

 <P>
 <PRE>
 % bluegnu tc001
 </PRE>
 <P>
 The last test you can run will fail in its simple form:

 <P>
 <PRE>
 % bluegnu tc002
 </PRE>
 <P>
 But will pass if you execute the test as follows:

 <P>
 <PRE>
 % bluegnu tc002[English]
 </PRE>
 <P>
 This is because the test scripts need a test case identifier to find
 the correct benchmark code.

 <P>

 <H1><A NAME="SECTION00050000000000000000">
 Changes</A>
 </H1>

 <H2><A NAME="SECTION00051000000000000000">
 Version 2.0.3</A>
 </H2>
 This being the first public release it is not to useful to list all
 the changes. BlueGnu has been modeled after DejaGnu and is a complete
 new implementation which has been tested thoroughly. When
 documentation is being written more changes will be made. An example
 of some of these changes as a result of this documentation effort can
 be found in the test-suites ts<code>_</code>001, ts<code>_</code>002, and
 ts<code>_</code>003. The first two are not as easy to write as the
 third. The test suite ts<code>_</code>001 is a script implementation of the
 command line:
 <PRE>
 % cd bluegnu2.0.3/testsets
 % bluegnu examples/tc002[English=B] \
 &gt; "examples/tc002[Dutch=B]={MSG=Hallo Wereld}"
 </PRE>This may be useful for simple tests but when you want to write more
 complex test-suite scripts you would like some more flexibility, so two
 procedures were introduced, which are shown in test-suite ts<code>_</code>002. This
 makes writing rather complex so the procedures have become part of
 the procedures 'appendQueue', 'prependQueue', and 'runtest'. The
 resulting script is shown in test-suit ts<code>_</code>003.

 <P>
 Changes like this will be made in the future!

 <P>

 <H1><A NAME="SECTION00060000000000000000">
 Future Enhancements</A>
 </H1>
 The following enhancements are being planned:
 <UL>
 <LI>Target code will be made into a class with methods 'start',
 'load', 'exit', and 'version'. Instead of the current
 '&lt;target&gt;<code>_</code>start', '&lt;target&gt;<code>_</code>load', '&lt;target&gt;<code>_</code>exit', and
 '&lt;target&gt;<code>_</code>version', which have been taken from DejaGnu.

 <P>
 <LI>Procedures will be created that make it easy to test WEB
 application from the framework.

 <P>
 <LI>Other enhancements will be made depending on the use of the
 framework in testing different applications.

	% cd bluegnu2.0.3/testsets
	% bluegnu examples/tc002[English=B] \
	> "examples/tc002[Dutch=B]={MSG=Hallo Wereld}"
	</PRE>This may be useful for simple tests but when you want to write more
	complex test-suite scripts you would like some more flexibility, so two
	procedures were introduced, which are shown in test-suite ts<code>_</code>002. This
	makes writing rather complex so the procedures have become part of
	the procedures 'appendQueue', 'prependQueue', and 'runtest'. The
	resulting script is shown in test-suit ts<code>_</code>003.

	<P>
	Changes like this will be made in the future!

	Future Enhancements</A>
	</H1>
	The following enhancements are being planned:
	<UL>
	<LI>Target code will be made into a class with methods 'start',
	'load', 'exit', and 'version'. Instead of the current
	'<target><code>_</code>start', '<target><code>_</code>load', '<target><code>_</code>exit', and
	'<target><code>_</code>version', which have been taken from DejaGnu.

	<P>
	<LI>Procedures will be created that make it easy to test WEB
	application from the framework.

	<P>
	<LI>Other enhancements will be made depending on the use of the
	framework in testing different applications.
