<para>It is desirable to declare standard libraries available on a
given system. Putting target declaration in Jamfile is not really
good, since locations of the libraries can vary. The solution is
to put the following to site-config.jam.</para>
to declare the targets in site-config.jam:</para>
<programlisting>
import project ;
project.initialize $(__name__) ;
project site-config ;
lib zlib : : &lt;name&gt;z ;
</programlisting>
<para>The second line allows this module to act as project. The
third line gives id to this project &#x2014; it really has no location

<para>Recall that both <filename>site-config.jam</filename> and
<filename>user-config.jam</filename> are projects, and everything
you can do in a Jamfile you can do in those files. So, you declare
a project id and a target. Now, one can write:
<programlisting>
exe hello : hello.cpp /site-config//zlib ;
</programlisting>
