The nhc98 compiler is distributed under the terms of the licence below.
The core of the hmake tool is copyright © Thomas Hallgren, 1991-1997. (Code is incorporated from the earlier tools hbcmake and nhcmake.) Many modifications to hmake are copyright © Malcolm Wallace, 1998-2007. Hmake interactive is copyright © Malcolm Wallace, 2000. hmake-config is copyright © Malcolm Wallace, 2002-2004. The hmake toolset is distributed under the terms of the licence below.
The cpphs tool is copyright © to Malcolm Wallace 2004-2010. Cpphs is distributed under the terms of the GNU LGPL.
The hp2graph tool is copyright © David Wakeling and Niklas Röjemo, 1991-1996. Hp2graph is distributed under the terms of the licence below.
The HOOD Observe library and graphical browser are copyright © Andy Gill, 2000. The HOOD graphical browser incorporates open source Java components copyright © MicroStar Inc, 1999. (Please read their separate licence.)
The Random library is copied direct from Hugs, which has a separate BSD-style licence. The implementation of Random is copyright © Lennart Augustsson, with modifications by Sigbjorn Finne. Some parts of the implementation of the Time library were also contributed by Lennart.
The hierarchical libraries in the base package are copyright © University of Glasgow, and are distributed under a separate BSD-style licence.
Other hierarchical libraries packages are copyright © their respective authors, and are distributed under varying licence conditions. Please see individual package documentation for details.
The development of nhc98 (and its predecessor nhc13) has been supported by NUTEK (Sweden), Canon Research Europe Ltd., EPSRC (UK), and the Universities of Chalmers (Sweden) and York (UK).
It is the intention that this software be "freely available" in the Gnu (http://www.gnu.org/) and Open Source (http://www.opensource.org/) traditions. The following is a brief statement of the rights and restrictions attached to this software distribution. This is version 2 of the licence (previous version), and governs this copy of the software. We may publish modified terms and conditions at a later date, and if you wish, you may apply any successor licence (when published), or the GNU GPL, to this software as an alternative to the current terms. (Note that if you convert your copy of the licence to the GPL, you will not be able to convert it back later, and nor can anyone who receives a copy from you.)
If you are not sure about any of the terms of this licence, please contact us to discuss your requirements. (Primary contact: [email protected])
You may use, re-distribute, and modify this software, in whole or in part, in source or binary form, but you must include without alteration all the relevant copyright notices. (You may of course remove a copyright notice pertaining to a piece of software no longer included in your distribution.) You may add your own additional copyright notices for any modifications or additions to this software that you distribute. If you distribute a modified version, you must also provide corresponding source code for it; any modifications must be described in the documentation; and you must clearly indicate that the software has been modified, for instance by changing the name of the executable or its version number, or by some other method.
You must not restrict anyone else's rights to use, re-distribute or modify any part of this software. Distributions of standard or modified versions of this software must retain this licence (or its successor), or at your choice, be distributed instead under the GNU GPL.
In addition, you are explicitly granted the right to re-use a small number of modules of this software in the creation of new software which does not perform substantially the same task as this software, for instance, by re-using a parser but not the entire compiler. In such a case, you are not forced to place the new software under this or any other licence, but you must ensure that:
Programs, object files, and intermediate files produced as output by this software do not fall under this copyright statement and are not governed by the terms of this licence. You are free to use them (or restrict their use) as you like. In particular, the inclusion of nhc98's runtime system and the Haskell'98 libraries in a resultant program, solely by virtue of being compiled and linked by nhc98, does not place any restrictions on your use of your own program. However, you should check carefully the licence of any other library you use in your program, whether supplied together with this software or not.
UNLESS OTHERWISE STATED IN WRITING, THIS SOFTWARE IS SUPPLIED "AS IS" AND WITHOUT ANY WARRANTY, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION THE IMPLIED WARRANTIES OF MERCHANTIBILITY AND FITNESS FOR A PARTICULAR PURPOSE. NEITHER THE AUTHORS, COPYRIGHT HOLDERS, NOR ANY OTHER PARTY WHO REDISTRIBUTES THIS SOFTWARE SHALL BE LIABLE FOR DAMAGES, HOWSOEVER CAUSED, ARISING OUT OF THE USE OF THIS SOFTWARE. USE AT YOUR OWN RISK.
