+The Unix configuration script "configure" was produced with GNU Autoconf.

+The same holds for its supporting scripts (config.guess, config.sub,
+ltmain.sh).  Another support script, install-sh, is copyright by X Consortium
+but is also freely distributable.
+
+The IJG distribution formerly included code to read and write GIF files.
+To avoid entanglement with the Unisys LZW patent, GIF reading support has
+been removed altogether, and the GIF writer has been simplified to produce
+"uncompressed GIFs".  This technique does not use the LZW algorithm; the
+resulting GIF files are larger than usual, but are readable by all standard
+GIF decoders.

+
+1. License Terms.
+
+1.1. Patent License. Subject to the terms and conditions of this License, each
+     Licensor, on behalf of itself and successors in interest and assigns,
+     grants Licensee a non-sublicensable, perpetual, worldwide, non-exclusive,
+     no-charge, royalty-free, irrevocable (except as expressly stated in this
+     License) patent license to its Necessary Claims to make, use, sell, offer
+     for sale, import or distribute any Implementation.
+
+1.2. Conditions.
+
+1.2.1. Availability. As a condition to the grant of rights to Licensee to make,
+       sell, offer for sale, import or distribute an Implementation under

+       a. For distribution in source code, by including this License in the
+          root directory of the source code with its Implementation.
+
+       b. For distribution in any other form (including binary, object form,

+
+1.3. Defensive Termination. If any Licensee, its Affiliates, or its agents
+     initiates patent litigation or files, maintains, or voluntarily
+     participates in a lawsuit against another entity or any person asserting
+     that any Implementation infringes Necessary Claims, any patent licenses
+     granted under this License directly to the Licensee are immediately
+     terminated as of the date of the initiation of action unless 1) that suit
+     was in response to a corresponding suit regarding an Implementation first
+     brought against an initiating entity, or 2) that suit was brought to
+     enforce the terms of this License (including intervention in a third-party
+     action by a Licensee).
+
+1.4. Disclaimers. The Reference Implementation and Specification are provided

+     (express, implied, or otherwise), including implied warranties of
+     merchantability, non-infringement, fitness for a particular purpose, or
+     title, related to the material. IN NO EVENT WILL LICENSOR BE LIABLE TO
+     ANY OTHER PARTY FOR LOST PROFITS OR ANY FORM OF INDIRECT, SPECIAL,
+     INCIDENTAL, OR CONSEQUENTIAL DAMAGES OF ANY CHARACTER FROM ANY CAUSES OF
+     ACTION OF ANY KIND WITH RESPECT TO THIS LICENSE, WHETHER BASED ON BREACH
