# The FreeType Project LICENSE
# ----------------------------
#
# Copyright 1996-1999 by
# David Turner, Robert Wilhelm, and Werner Lemberg
#
#
#
# Introduction
# ============
#
# The FreeType Project is distributed in several archive packages;
# some of them may contain, in addition to the FreeType font engine,
# various tools and contributions which rely on, or relate to, the
# FreeType Project.
#
# This license applies to all files found in such packages, and
# which do not fall under their own explicit license. The license
# affects thus the FreeType font engine, the test programs,
# documentation and makefiles, at the very least.
#
# This license was inspired by the BSD, Artistic, and IJG
# (Independent JPEG Group) licenses, which all encourage inclusion
# and use of free software in commercial and freeware products
# alike. As a consequence, its main points are that:
#
# o We don't promise that this software works. However, we are be
# interested in any kind of bug reports. (`as is' distribution)
#
# o You can use this software for whatever you want, in parts or
# full form, without having to pay us. (`royalty-free' usage)
#
# o You may not pretend that you wrote this software. If you use
# it, or only parts of it, in a program, you must acknowledge
# somewhere in your documentation that you've used the FreeType
# code. (`credits')
#
# We specifically permit and encourage the inclusion of this
# software, with or without modifications, in commercial products,
# provided that all warranty or liability claims are assumed by the
# product vendor.
#
#
# Legal Terms
# ===========
#
# 0. Definitions
# --------------
#
# Throughout this license, the terms `package', `FreeType Project',
# and `FreeType archive' refer to the set of files originally
# distributed by the authors (David Turner, Robert Wilhelm, and
# Werner Lemberg) as the `FreeType project', be they named as alpha,
# beta or final release.
#
# `You' refers to the licensee, or person using the project, where
# `using' is a generic term including compiling the project's source
# code as well as linking it to form a `program' or `executable'.
# This program is referred to as `a program using the FreeType
# engine'.
#
# This license applies to all files distributed in the original
# FreeType archive, including all source code, binaries and
# documentation, unless otherwise stated in the file in its
# original, unmodified form as distributed in the original archive.
# If you are unsure whether or not a particular file is covered by
# this license, you must contact us to verify this.
#
# The FreeType project is copyright (C) 1996-1999 by David Turner,
# Robert Wilhelm, and Werner Lemberg. All rights reserved except as
# specified below.
#
# 1. No Warranty
# --------------
#
# THE FREETYPE ARCHIVE IS PROVIDED `AS IS' WITHOUT WARRANTY OF ANY
# KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
# WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
# PURPOSE. IN NO EVENT WILL ANY OF THE AUTHORS OR COPYRIGHT HOLDERS
# BE LIABLE FOR ANY DAMAGES CAUSED BY THE USE OR THE INABILITY TO
# USE, OF THE FREETYPE PROJECT.
#
# As you have not signed this license, you are not required to
# accept it. However, as the FreeType project is copyrighted
# material, only this license, or another one contracted with the
# authors, grants you the right to use, distribute, and modify it.
# Therefore, by using, distributing, or modifying the FreeType
# project, you indicate that you understand and accept all the terms
# of this license.
#
# 2. Redistribution
# -----------------
#
# Redistribution and use in source and binary forms, with or without
# modification, are permitted provided that the following conditions
# are met:
#
# o Redistribution of source code must retain this license file
# (`licence.txt') unaltered; any additions, deletions or changes
# to the original files must be clearly indicated in
# accompanying documentation. The copyright notices of the
# unaltered, original files must be preserved in all copies of
# source files.
#
# o Redistribution in binary form must provide a disclaimer that
# states that the software is based in part of the work of the
# FreeType Team, in the distribution documentation. We also
# encourage you to put an URL to the FreeType web page in your
# documentation, though this isn't mandatory.
#
# These conditions apply to any software derived from or based on
# the FreeType code, not just the unmodified files. If you use our
# work, you must acknowledge us. However, no fee need be paid to
# us.
#
# 3. Advertising
# --------------
#
# The names of FreeType's authors and contributors may not be used
# to endorse or promote products derived from this software without
# specific prior written permission.
#
# We suggest, but do not require, that you use one or more of the
# following phrases to refer to this software in your documentation
# or advertising materials: `FreeType Project', `FreeType Engine',
# `FreeType library', or `FreeType Distribution'.
#
# 4. Contacts
# -----------
#
# There are two mailing lists related to FreeType:
#
# o freetype@freetype.org
#
# Discusses general use and applications of FreeType, as well as
# future and wanted additions to the library and distribution.
# If you are looking for support, start in this list if you
# haven't found anything to help you in the documentation.
#
# o devel@freetype.org
#
# Discusses bugs, as well as engine internals, design issues,
# specific licenses, porting, etc.
#
# o http://www.freetype.org
#
# Holds the current FreeType web page, which will allow you to
# download our latest development version and read online
# documentation.
#
# You can also contact us individually at:
#
# David Turner <david.turner@freetype.org>
