#********************IMPORTANT DRAKVUF LICENSE TERMS**********************#
# #
# DRAKVUF (C) 2014-2016 Tamas K Lengyel. #
# Tamas K Lengyel is hereinafter referred to as the author. #
# This program is free software; you may redistribute and/or modify it #
# under the terms of the GNU General Public License as published by the #
# Free Software Foundation; Version 2 ("GPL"), BUT ONLY WITH ALL OF THE #
# CLARIFICATIONS AND EXCEPTIONS DESCRIBED HEREIN. This guarantees your #
# right to use, modify, and redistribute this software under certain #
# conditions. If you wish to embed DRAKVUF technology into proprietary #
# software, alternative licenses can be aquired from the author. #
# #
# Note that the GPL places important restrictions on "derivative works", #
# yet it does not provide a detailed definition of that term. To avoid #
# misunderstandings, we interpret that term as broadly as copyright law #
# allows. For example, we consider an application to constitute a #
# derivative work for the purpose of this license if it does any of the #
# following with any software or content covered by this license #
# ("Covered Software"): #
# #
# o Integrates source code from Covered Software. #
# #
# o Reads or includes copyrighted data files. #
# #
# o Is designed specifically to execute Covered Software and parse the #
# results (as opposed to typical shell or execution-menu apps, which will #
# execute anything you tell them to). #
# #
# o Includes Covered Software in a proprietary executable installer. The #
# installers produced by InstallShield are an example of this. Including #
# DRAKVUF with other software in compressed or archival form does not #
# trigger this provision, provided appropriate open source decompression #
# or de-archiving software is widely available for no charge. For the #
# purposes of this license, an installer is considered to include Covered #
# Software even if it actually retrieves a copy of Covered Software from #
# another source during runtime (such as by downloading it from the #
# Internet). #
# #
# o Links (statically or dynamically) to a library which does any of the #
# above. #
# #
# o Executes a helper program, module, or script to do any of the above. #
# #
# This list is not exclusive, but is meant to clarify our interpretation #
# of derived works with some common examples. Other people may interpret #
# the plain GPL differently, so we consider this a special exception to #
# the GPL that we apply to Covered Software. Works which meet any of #
# these conditions must conform to all of the terms of this license, #
# particularly including the GPL Section 3 requirements of providing #
# source code and allowing free redistribution of the work as a whole. #
# #
# Any redistribution of Covered Software, including any derived works, #
# must obey and carry forward all of the terms of this license, including #
# obeying all GPL rules and restrictions. For example, source code of #
# the whole work must be provided and free redistribution must be #
# allowed. All GPL references to "this License", are to be treated as #
# including the terms and conditions of this license text as well. #
# #
# Because this license imposes special exceptions to the GPL, Covered #
# Work may not be combined (even as part of a larger work) with plain GPL #
# software. The terms, conditions, and exceptions of this license must #
# be included as well. This license is incompatible with some other open #
# source licenses as well. In some cases we can relicense portions of #
# DRAKVUF or grant special permissions to use it in other open source #
# software. Please contact tamas.k.lengyel@gmail.com with any such #
# requests. Similarly, we don't incorporate incompatible open source #
# software into Covered Software without special permission from the #
# copyright holders. #
# #
# If you have any questions about the licensing restrictions on using #
# DRAKVUF in other works, are happy to help. As mentioned above, #
# alternative license can be requested from the author to integrate #
# DRAKVUF into proprietary applications and appliances. Please email #
# tamas.k.lengyel@gmail.com for further information. #
# #
# If you have received a written license agreement or contract for #
# Covered Software stating terms other than these, you may choose to use #
# and redistribute Covered Software under those terms instead of these. #
# #
# Source is provided to this software because we believe users have a #
# right to know exactly what a program is going to do before they run it. #
# This also allows you to audit the software for security holes. #
# #
# Source code also allows you to port DRAKVUF to new platforms, fix bugs, #
# and add new features. You are highly encouraged to submit your changes #
# on https://github.com/tklengyel/drakvuf, or by other methods. #
# By sending these changes, it is understood (unless you specify #
# otherwise) that you are offering unlimited, non-exclusive right to #
# reuse, modify, and relicense the code. DRAKVUF will always be #
# available Open Source, but this is important because the inability to #
# relicense code has caused devastating problems for other Free Software #
# projects (such as KDE and NASM). #
# To specify special license conditions of your contributions, just say #
# so when you send them. #
# #
# This program is distributed in the hope that it will be useful, but #
# WITHOUT ANY WARRANTY; without even the implied warranty of #
# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the DRAKVUF #
