yasm-1.3.0/Artistic.txt:

			 The "Artistic License"

				Preamble

The intent of this document is to state the conditions under which a

Package may be copied, such that the Copyright Holder maintains some

semblance of artistic control over the development of the package,

while giving the users of the package the right to use and distribute

the Package in a more-or-less customary fashion, plus the right to make

reasonable modifications.

Definitions:

	"Package" refers to the collection of files distributed by the

	Copyright Holder, and derivatives of that collection of files

	created through textual modification.

	"Standard Version" refers to such a Package if it has not been

	modified, or has been modified in accordance with the wishes

	of the Copyright Holder as specified below.

	"Copyright Holder" is whoever is named in the copyright or

	copyrights for the package.

	"You" is you, if you're thinking about copying or distributing

	this Package.

	"Reasonable copying fee" is whatever you can justify on the

	basis of media cost, duplication charges, time of people involved,

	and so on.  (You will not be required to justify it to the

	Copyright Holder, but only to the computing community at large

	as a market that must bear the fee.)

	"Freely Available" means that no fee is charged for the item

	itself, though there may be fees involved in handling the item.

	It also means that recipients of the item may redistribute it

	under the same conditions they received it.

1. You may make and give away verbatim copies of the source form of the

Standard Version of this Package without restriction, provided that you

duplicate all of the original copyright notices and associated disclaimers.

2. You may apply bug fixes, portability fixes and other modifications

derived from the Public Domain or from the Copyright Holder.  A Package

modified in such a way shall still be considered the Standard Version.

3. You may otherwise modify your copy of this Package in any way, provided

that you insert a prominent notice in each changed file stating how and

when you changed that file, and provided that you do at least ONE of the

following:

    a) place your modifications in the Public Domain or otherwise make them

    Freely Available, such as by posting said modifications to Usenet or

    an equivalent medium, or placing the modifications on a major archive

    site such as uunet.uu.net, or by allowing the Copyright Holder to include

    your modifications in the Standard Version of the Package.

    b) use the modified Package only within your corporation or organization.

    c) rename any non-standard executables so the names do not conflict

    with standard executables, which must also be provided, and provide

    a separate manual page for each non-standard executable that clearly

    documents how it differs from the Standard Version.

    d) make other distribution arrangements with the Copyright Holder.

4. You may distribute the programs of this Package in object code or

executable form, provided that you do at least ONE of the following:

    a) distribute a Standard Version of the executables and library files,

    together with instructions (in the manual page or equivalent) on where

    to get the Standard Version.

    b) accompany the distribution with the machine-readable source of

    the Package with your modifications.

    c) give non-standard executables non-standard names, and clearly

    document the differences in manual pages (or equivalent), together

    with instructions on where to get the Standard Version.

    d) make other distribution arrangements with the Copyright Holder.

5. You may charge a reasonable copying fee for any distribution of this

Package.  You may charge any fee you choose for support of this

Package.  You may not charge a fee for this Package itself.  However,

you may distribute this Package in aggregate with other (possibly

commercial) programs as part of a larger (possibly commercial) software

distribution provided that you do not advertise this Package as a

product of your own.  You may embed this Package's interpreter within

an executable of yours (by linking); this shall be construed as a mere

form of aggregation, provided that the complete Standard Version of the

interpreter is so embedded.

6. The scripts and library files supplied as input to or produced as

output from the programs of this Package do not automatically fall

under the copyright of this Package, but belong to whoever generated

them, and may be sold commercially, and may be aggregated with this

Package.  If such scripts or library files are aggregated with this

Package via the so-called "undump" or "unexec" methods of producing a

binary executable image, then distribution of such an image shall

neither be construed as a distribution of this Package nor shall it

fall under the restrictions of Paragraphs 3 and 4, provided that you do

not represent such an executable image as a Standard Version of this

Package.

7. C subroutines (or comparably compiled subroutines in other

languages) supplied by you and linked into this Package in order to

emulate subroutines and variables of the language defined by this

Package shall not be considered part of this Package, but are the

equivalent of input as in Paragraph 6, provided these subroutines do

not change the language in any way that would cause it to fail the

regression tests for the language.

8. Aggregation of this Package with a commercial distribution is always

permitted provided that the use of this Package is embedded; that is,

when no overt attempt is made to make this Package's interfaces visible

to the end user of the commercial distribution.  Such use shall not be

construed as a distribution of this Package.

9. The name of the Copyright Holder may not be used to endorse or promote

products derived from this software without specific prior written permission.

10. THIS PACKAGE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR

IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED

WARRANTIES OF MERCHANTIBILITY AND FITNESS FOR A PARTICULAR PURPOSE.

yasm-1.3.0/GNU_GPL-2.0:

		    GNU GENERAL PUBLIC LICENSE

		       Version 2, June 1991

 Copyright (C) 1989, 1991 Free Software Foundation, Inc.

                       51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA

 Everyone is permitted to copy and distribute verbatim copies

 of this license document, but changing it is not allowed.

			    Preamble

  The licenses for most software are designed to take away your

freedom to share and change it.  By contrast, the GNU General Public

License is intended to guarantee your freedom to share and change free

software--to make sure the software is free for all its users.  This

General Public License applies to most of the Free Software

Foundation's software and to any other program whose authors commit to

using it.  (Some other Free Software Foundation software is covered by

the GNU Library General Public License instead.)  You can apply it to

your programs, too.

  When we speak of free software, we are referring to freedom, not

price.  Our General Public Licenses are designed to make sure that you

have the freedom to distribute copies of free software (and charge for

this service if you wish), that you receive source code or can get it

if you want it, that you can change the software or use pieces of it

in new free programs; and that you know you can do these things.

  To protect your rights, we need to make restrictions that forbid

anyone to deny you these rights or to ask you to surrender the rights.

These restrictions translate to certain responsibilities for you if you

distribute copies of the software, or if you modify it.

  For example, if you distribute copies of such a program, whether

gratis or for a fee, you must give the recipients all the rights that

you have.  You must make sure that they, too, receive or can get the

source code.  And you must show them these terms so they know their

rights.

  We protect your rights with two steps: (1) copyright the software, and

(2) offer you this license which gives you legal permission to copy,

distribute and/or modify the software.

  Also, for each author's protection and ours, we want to make certain

that everyone understands that there is no warranty for this free

software.  If the software is modified by someone else and passed on, we

want its recipients to know that what they have is not the original, so

that any problems introduced by others will not reflect on the original

authors' reputations.

  Finally, any free program is threatened constantly by software

patents.  We wish to avoid the danger that redistributors of a free

program will individually obtain patent licenses, in effect making the

program proprietary.  To prevent this, we have made it clear that any

patent must be licensed for everyone's free use or not licensed at all.

  The precise terms and conditions for copying, distribution and

modification follow.

		    GNU GENERAL PUBLIC LICENSE

   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

  0. This License applies to any program or other work which contains

a notice placed by the copyright holder saying it may be distributed

under the terms of this General Public License.  The "Program", below,

refers to any such program or work, and a "work based on the Program"

means either the Program or any derivative work under copyright law:

that is to say, a work containing the Program or a portion of it,

either verbatim or with modifications and/or translated into another

language.  (Hereinafter, translation is included without limitation in

the term "modification".)  Each licensee is addressed as "you".

Activities other than copying, distribution and modification are not

covered by this License; they are outside its scope.  The act of

running the Program is not restricted, and the output from the Program

is covered only if its contents constitute a work based on the

Program (independent of having been made by running the Program).

Whether that is true depends on what the Program does.

  1. You may copy and distribute verbatim copies of the Program's

source code as you receive it, in any medium, provided that you

conspicuously and appropriately publish on each copy an appropriate

copyright notice and disclaimer of warranty; keep intact all the

notices that refer to this License and to the absence of any warranty;

and give any other recipients of the Program a copy of this License

along with the Program.

You may charge a fee for the physical act of transferring a copy, and

you may at your option offer warranty protection in exchange for a fee.

  2. You may modify your copy or copies of the Program or any portion

of it, thus forming a work based on the Program, and copy and

distribute such modifications or work under the terms of Section 1

above, provided that you also meet all of these conditions:

    a) You must cause the modified files to carry prominent notices

    stating that you changed the files and the date of any change.

    b) You must cause any work that you distribute or publish, that in

    whole or in part contains or is derived from the Program or any

    part thereof, to be licensed as a whole at no charge to all third

    parties under the terms of this License.

    c) If the modified program normally reads commands interactively

    when run, you must cause it, when started running for such

    interactive use in the most ordinary way, to print or display an

    announcement including an appropriate copyright notice and a

    notice that there is no warranty (or else, saying that you provide

    a warranty) and that users may redistribute the program under

    these conditions, and telling the user how to view a copy of this

    License.  (Exception: if the Program itself is interactive but

    does not normally print such an announcement, your work based on

    the Program is not required to print an announcement.)

These requirements apply to the modified work as a whole.  If

identifiable sections of that work are not derived from the Program,

and can be reasonably considered independent and separate works in

themselves, then this License, and its terms, do not apply to those

sections when you distribute them as separate works.  But when you

distribute the same sections as part of a whole which is a work based

on the Program, the distribution of the whole must be on the terms of

this License, whose permissions for other licensees extend to the

entire whole, and thus to each and every part regardless of who wrote it.

Thus, it is not the intent of this section to claim rights or contest

your rights to work written entirely by you; rather, the intent is to

exercise the right to control the distribution of derivative or

collective works based on the Program.

In addition, mere aggregation of another work not based on the Program

with the Program (or with a work based on the Program) on a volume of

a storage or distribution medium does not bring the other work under

the scope of this License.

  3. You may copy and distribute the Program (or a work based on it,

under Section 2) in object code or executable form under the terms of

Sections 1 and 2 above provided that you also do one of the following:

    a) Accompany it with the complete corresponding machine-readable

    source code, which must be distributed under the terms of Sections

    1 and 2 above on a medium customarily used for software interchange; or,

    b) Accompany it with a written offer, valid for at least three

    years, to give any third party, for a charge no more than your

    cost of physically performing source distribution, a complete

    machine-readable copy of the corresponding source code, to be

    distributed under the terms of Sections 1 and 2 above on a medium

    customarily used for software interchange; or,

    c) Accompany it with the information you received as to the offer

    to distribute corresponding source code.  (This alternative is

    allowed only for noncommercial distribution and only if you

    received the program in object code or executable form with such

    an offer, in accord with Subsection b above.)

The source code for a work means the preferred form of the work for

making modifications to it.  For an executable work, complete source

code means all the source code for all modules it contains, plus any

associated interface definition files, plus the scripts used to

control compilation and installation of the executable.  However, as a

special exception, the source code distributed need not include

anything that is normally distributed (in either source or binary

form) with the major components (compiler, kernel, and so on) of the

operating system on which the executable runs, unless that component

itself accompanies the executable.

If distribution of executable or object code is made by offering

access to copy from a designated place, then offering equivalent

access to copy the source code from the same place counts as

distribution of the source code, even though third parties are not

compelled to copy the source along with the object code.

  4. You may not copy, modify, sublicense, or distribute the Program

except as expressly provided under this License.  Any attempt

otherwise to copy, modify, sublicense or distribute the Program is

void, and will automatically terminate your rights under this License.

However, parties who have received copies, or rights, from you under

this License will not have their licenses terminated so long as such

parties remain in full compliance.

  5. You are not required to accept this License, since you have not

signed it.  However, nothing else grants you permission to modify or

distribute the Program or its derivative works.  These actions are

prohibited by law if you do not accept this License.  Therefore, by

modifying or distributing the Program (or any work based on the

Program), you indicate your acceptance of this License to do so, and

all its terms and conditions for copying, distributing or modifying

the Program or works based on it.

  6. Each time you redistribute the Program (or any work based on the

Program), the recipient automatically receives a license from the

original licensor to copy, distribute or modify the Program subject to

these terms and conditions.  You may not impose any further

restrictions on the recipients' exercise of the rights granted herein.

You are not responsible for enforcing compliance by third parties to

this License.

  7. If, as a consequence of a court judgment or allegation of patent

infringement or for any other reason (not limited to patent issues),

conditions are imposed on you (whether by court order, agreement or

otherwise) that contradict the conditions of this License, they do not

excuse you from the conditions of this License.  If you cannot

distribute so as to satisfy simultaneously your obligations under this

License and any other pertinent obligations, then as a consequence you

may not distribute the Program at all.  For example, if a patent

license would not permit royalty-free redistribution of the Program by

all those who receive copies directly or indirectly through you, then

the only way you could satisfy both it and this License would be to

refrain entirely from distribution of the Program.

If any portion of this section is held invalid or unenforceable under

any particular circumstance, the balance of the section is intended to

apply and the section as a whole is intended to apply in other

circumstances.

It is not the purpose of this section to induce you to infringe any

patents or other property right claims or to contest validity of any

such claims; this section has the sole purpose of protecting the

integrity of the free software distribution system, which is

implemented by public license practices.  Many people have made

generous contributions to the wide range of software distributed

through that system in reliance on consistent application of that

system; it is up to the author/donor to decide if he or she is willing

to distribute software through any other system and a licensee cannot

impose that choice.

This section is intended to make thoroughly clear what is believed to

be a consequence of the rest of this License.

  8. If the distribution and/or use of the Program is restricted in

certain countries either by patents or by copyrighted interfaces, the

original copyright holder who places the Program under this License

may add an explicit geographical distribution limitation excluding

those countries, so that distribution is permitted only in or among

countries not thus excluded.  In such case, this License incorporates

the limitation as if written in the body of this License.

  9. The Free Software Foundation may publish revised and/or new versions

of the General Public License from time to time.  Such new versions will

be similar in spirit to the present version, but may differ in detail to

address new problems or concerns.

Each version is given a distinguishing version number.  If the Program

specifies a version number of this License which applies to it and "any

later version", you have the option of following the terms and conditions

either of that version or of any later version published by the Free

Software Foundation.  If the Program does not specify a version number of

this License, you may choose any version ever published by the Free Software

Foundation.

  10. If you wish to incorporate parts of the Program into other free
