<a name="index-HOL-Light-Proof-General"></a>

<p>HOL Light Proof General is a &quot;technology demonstration&quot; of Proof General
for HOL Light.  This means that only a basic instantiation has been
provided, and that it is not yet supported as a maintained instantiation
of Proof General.
</p>
<p>HOL Light Proof General has basic script management support, with a
little bit of decoration of scripts and output.  It does not rely on a
modified version of HOL Light, so the pattern matching may be fragile in
certain cases.  
</p>

<p>See the <samp>example.ml</samp> file for a demonstration proof script
which works with Proof General.
</p>
<p>Note that HOL Light Proof Script proof scripts often use batch-oriented
single step tactic proofs, but Proof General does not (yet) offer an
easy way to edit these kind of proofs.  They will replay simply as a
single step proof and you will need to convert from the interactive to
batch form as usual if you wish to obtain batch proofs.  Also note that
Proof General does not contain an SML parser, so there can be problems
if you write complex ML in proof scripts.
</p>
<p>HOL Light is the most recently tested version of HOL with Proof General,
but the Proof General distribution also contains experimental support
for HOL 4 (aka HOL 98).  To improve this older version, or to support a
new HOL variant, a few of the settings probably need to be tweaked to
cope with small differences in output between the systems.  Please let
us know if you try this out and want help.  We welcome any interested
collaborators from the HOL communities to help improve Proof General as
an interface for HOL provers.
