+The "Box Backup GPL" license follows:
 ---------------------------------------------------------------------
+The Box Backup GPL is based on the GPLv2 (GNU General Public License
+version 2 or later) as published by the Free Software Foundation.
+However, it includes optional exceptions which allow linking with
+OpenSSL and Microsoft VSS, listed below. This means that Box Backup
+is not under pure GPLv2 as published by the Free Software Foundation.
+These are the only differences between the Box Backup GPL license and
+the original GPL from the Free Software Foundation.
+
+Please note that while the Box Backup GPL is similar in spirit to the
+original GPL, it is not fully compatible. Because of these optional
+exceptions, you may not include or combine fully GPL source code 
+(such as the GNU readline library) with Box Backup, or distribute the
+resulting binaries, under the Box Backup GPL license, without
+specific permission from the authors of such code. You may do so
+under the pure GPL license, by omitting the optional exclusion clauses
+below, however you may not legally link such code with OpenSSL or
+Microsoft VSS, which may limit the usefulness or functionality of the
+resulting code.
+
+The license exemption section below was based on the license of the
+Bacula project
+[http://bacula.git.sourceforge.net/git/gitweb.cgi?p=bacula/bacula;a=blob_plain;f=bacula/LICENSE;hb=HEAD].
+
+For the most part, Box Backup is licensed under the GPL version 2
+[http://www.gnu.org/licenses/old-licenses/gpl-2.0.txt].
+The sections that follow are optional exemptions to the GPL version 2
+license, that apply to code that is copyrighted by Ben Summers and
+Contributors.
+
+Linking: 
+As a special exception to the GPLv2, the Box Backup Project gives
+permission to link any code falling under this license (the Box Backup
+GPL) with any software that can be downloaded from
+the OpenSSL website [http://www.openssl.org] under either the
+"OpenSSL License" or the "Original SSLeay License", and to distribute
+the linked executables under the terms of the "Box Backup GPL" license.
+
+As a special exception to the GPLv2, the Box Backup Project gives
+permission to link any code falling under this license (the Box Backup
+GPL) with any version of Microsoft's Volume Shadow Copy Service 7.2 SDK
+or Microsoft Windows Software Development Kit (SDK), including
+vssapi.lib, that can be downloaded from the Microsoft website
+[*.microsoft.com], and to distribute the linked executables under the
+terms of the "Box Backup GPL" license.
+
+The sections above are optional, and you may distribute the code that
+falls under this license under the original GPLv2 license by omitting
+them. The original GPLv2 license follows.
