77  The <b>MathQL-1 Suite for HELM</b> is implemented in <a
78  href="http://caml.inria.fr/">Caml</a> and is currently available through 
79 the <a href="http://www.cs.unibo.it/cgi-bin/cvsweb/helm/">HELM CVS repository</a>. 
80 The Suite provides the following&nbsp; software components:&nbsp; </p>
81        
82       <ol>
83   <li> The basic Caml package for MathQL-1 (<a
84  href="http://www.cs.unibo.it/cgi-bin/cvsweb/helm/ocaml/mathql/">mathql</a>)
85  provides a <a href="http://helm.cs.unibo.it/">HELM</a> independent Caml
86 representation of queries and query results, plus some general purpose utilities.</li>
87          
88       </ol>
89           
90       <ol start="2">
91   <li> The MathQL-1 interpreter (<a
92  href="http://www.cs.unibo.it/cgi-bin/cvsweb/helm/ocaml/mathql_interpreter/">mathql_interpreter</a>)
93 provides the proper search engine and is now HELM independent.</li>
94       </ol>
95       <ol start="3">
96         <li>The HELM query generator (<a
97  href="http://www.cs.unibo.it/cgi-bin/cvsweb/helm/ocaml/mathql_generator/">mathql_generator</a>)
98  allows to build specific kinds of MathQL-1 queries, which are meaningful
99 in the context of HELM, starting from a high-level description of the wanted
100  results. These queries are described at an abstract level in the following
101  paper:</li>

117  href="http://www.cs.unibo.it/cgi-bin/cvsweb/helm/mathql_test/">mathql_test</a>)
118  provides three textual interfaces (one for the basic package, one for the
119  interpreter and one for the query generator) with specific features meant
120  for testing.</li>

123   The current version of the Suite, realized entirely by F. Guidi, implements
124  MathQL-1 version 3 (i.e. MathQL-1.3). The newly implemented features, which
125  are not included in the official <a href="documentation.html">documentation</a>
