If the Ferret package was obtained as a part of the &GAP; distribution
from the <Q>Download</Q> section of the &GAP; website, you may proceed
to Section <Ref Sect="Compiling Binaries of the Ferret Package"/>.
Alternatively, the Ferret package may be installed using a separate archive,
for example, for an update or an installation in a non-default location
(see <Ref Sect="GAP Root Directories" BookName="ref"/>).
<P/>
Below we describe the installation procedure for the <File>.tar.gz</File>
archive format. Installation using other archive formats is performed in a
similar way.
<P/>
It may be unpacked in one of the following locations:
<List>
<Item>
in the <File>pkg</File> directory of your &GAP; 4 installation;
</Item>
<Item>
or in a directory named <File>.gap/pkg</File> in your home directory
(to be added to the &GAP; root directory unless &GAP; is started with
<C>-r</C> option);
</Item>
<Item>
or in a directory named <File>pkg</File> in another directory of your
choice (e.g. in the directory <File>mygap</File> in your home
directory).
</Item>
</List>
In the latter case one one must start &GAP; with the <C>-l</C> option,
e.g. if your private <F>pkg</F> directory is a subdirectory of
<F>mygap</F> in your home directory you might type:
<P/>
<C>gap -l ";myhomedir/mygap"</C>
<P/>
where <A>myhomedir</A> is the path to your home directory, which (since
&GAP; 4.3) may be replaced by a tilde (the empty path before the
semicolon is filled in by the default path of the &GAP; 4 home
directory).

<Section Label="Compiling Binaries of the Ferret Package">
<Heading>Compiling Binaries of the Ferret Package</Heading>
After unpacking the archive, go to the newly created <F>ferret</F> directory
and call <C>./configure</C> to use the default <C>../..</C> path to the
&GAP; home directory or <C>./configure <A>path</A></C> where <A>path</A> is
the path to the &GAP; home directory, if the package is being installed in a
non-default location. So for example if you install the package in the
<F>~/.gap/pkg</F> directory and the &GAP; home directory is <F>~/gap4r5</F>
then you have to call
<P/>
<Log><![CDATA[
./configure ../../../gap4r5/
]]></Log>
<P/>
This will fetch the architecture type for which &GAP; has been compiled
last and create a <F>Makefile</F>. Now simply call
<P/>
<Log><![CDATA[
make
]]></Log>
<P/>
to compile the binary and to install it in the appropriate place.

<Section Label="Loading the Ferret Package">
<Heading>Loading the Ferret Package</Heading>
To use the Ferret Package you have to request it explicitly. This is
done by calling <Ref Func="LoadPackage" BookName="ref"/>:
<P/>
<Example><![CDATA[
gap> LoadPackage("ferret");
true
]]></Example>
<P/>
If you want to load the Ferret package by default, you can put the
<C>LoadPackage</C> command into your <F>gaprc</F> file
(see Section <Ref Sect="The gap.ini and gaprc files" BookName="ref"/>).
