<h1>2 Installation</h1><p>
<p>
This package must be installed in the <code>pkg</code> subdirectory of any of
the <font face="Gill Sans,Helvetica,Arial">GAP</font> 4 root directories. We assume here that this is <code>/gap4/pkg</code>.
<p>
<pre>
cd /gap4/pkg
unzoo -x carat-2.1.zoo
</pre>
<p>
This creates a subdirectory <code>carat</code>, the home directory of the present
interface package. <font face="Gill Sans,Helvetica,Arial">CARAT</font> itself can be installed anywhere on your 
system. You only have to make sure <font face="Gill Sans,Helvetica,Arial">GAP</font> finds the <font face="Gill Sans,Helvetica,Arial">CARAT</font> binaries, 
by making a symbolic link from the <code>bin</code> subdirectory in <code>pkg/carat</code> to 
the <code>bin</code> subdirectory of <font face="Gill Sans,Helvetica,Arial">CARAT</font> itself. In our example, we install 
<font face="Gill Sans,Helvetica,Arial">CARAT</font> in <code>/gap4/pkg/carat</code> (the <font face="Gill Sans,Helvetica,Arial">CARAT</font> tar file should already be 
there):
<p>
<pre>
cd /gap4/pkg/carat
zcat carat-2.1b1.tgz | tar pxf -
ln -s carat-2.1b1/bin bin
cd carat-2.1b1
</pre>
<p>
This creates a subdirectory <code>carat-2.1b1</code>, the <font face="Gill Sans,Helvetica,Arial">CARAT</font> top level directory. 
You have to edit the Makefile in that directory. In particular, you have 
to set the variables TOPDIR (to <code>/gap4/pkg/carat/carat-2.1b1</code>), CC, and 
CFLAGS (to your favourite set of compiler options). Then do 
<p>
<pre>
make
</pre>
<p>
If you build for more than one architecture, make sure to do a 
'make clean' in between.
<p>
Like any other <font face="Gill Sans,Helvetica,Arial">GAP</font> 4 package, <font face="Gill Sans,Helvetica,Arial">CARAT</font> is then loaded in <font face="Gill Sans,Helvetica,Arial">GAP</font> with
<p>
<pre>
gap&gt; LoadPackage("carat");
true
</pre>
<p>
This package, together with <font face="Gill Sans,Helvetica,Arial">CARAT</font> itself, takes some 208Mb of disk space,
or more, depending on the system. Some 170Mb is taken by the catalog
of Q-classes if integer matrix groups up to dimension 6. If you want
to avoid unpacking this catalog, you can create empty subdirectories
<p>
<pre>
cd /gap4/pkg/carat/carat-2.1b1
mkdir tables
mkdir tables/qcatalog
</pre>
<p>
before making <font face="Gill Sans,Helvetica,Arial">CARAT</font>. If you want to unpack the catalog later, just
remove the empty directory <code>tables/qcatalog</code>, and do
<p>
<pre>
make Qcatalog
</pre>
