Floodgap Free Software License
The author of your software has chosen to distribute it under the Floodgap
Free Software License. Although this software is without cost, it is not
under Copyleft or GPL, and there are differences which you should read. Your
use of this software package constitutes your binding acceptance without
This software is without cost
The Floodgap Free Software License (FFSL) has one overriding mandate: that
software using it, or derivative works based on software that uses it, must be
free. By free we mean simply "free as in beer" -- you may put your work into
open or closed source packages as you see fit, whether or not you choose to
release your changes or updates publicly,
but you must not ask any fee for it.
(There are certain exceptions for for-profit use which we will discuss below.)
Definitions and terms
- The declared copyright owner of this software package.
- A pre-compiled or pre-interpreted
bytecode or machine language representation of a software
package not designed for further modification and tied to a particular
platform or architecture.
- Derivative work
- Any distribution (q.v.) that contains any modification to or deviation from
the official reference distribution (q.v.);
or any software package significantly based on or integrally including
the source code for its features,
including but not limited to supersets; subsets of
a significant proportion; in-place patched changes to source or binary files;
linking in as a library;
binary-only distributions if the original package included source (even if
the source was not modified prior to compilation);
or translations to another programming language,
architecture or operating system environment. Derivative works of packages
released under this license are also considered subject to this license.
However, a software
package that requires this package but does not include it or is
not based upon it,
even if it will not operate without it, is not considered a
derivative work. For example, interpreted programs requiring an interpreter
issued under this license, assuming they are not
distributed with any portion of the interpreter, are not derivative works.
- A packaged release of this software, either the author's original work
(the "reference distribution") or a derivative work based upon it.
- Reference distribution
- A packaged release of this software explicitly designated as the official
release, written by or on behalf of the Author with his or her explicit
designation as official. Only exact copies of the reference distribution may
be called reference distributions; all other forms are derivative works.
- Source code
- The human-readable programming instructions of the package which might be
easily read as text and subsequently edited, but requiring compilation or
interpretation into binary before being directly useable.
What you are permitted to do under this license
Pursuant to the remainder of the terms below,
- You may freely use, copy, and disseminate
this software package for any non-commercial purpose as well as the commercial
purposes permitted below.
- You may freely modify this package, including source code if available.
Your modifications need not be released,
although you are encouraged to do so.
- You may release your derivative works based upon this software in purely
binary (non-source) form if you choose. You are not obligated to release
any portion of your source code openly, although you are encouraged to do so.
- If this package is a tool used for generation, compilation or maintenance
of works, including but not limited to readable documents, software
packages or images (for example, compilers, interpreters,
editors, assemblers or typesetters), you may freely use it for that purpose,
commercial or otherwise, as the works made by this package are not
considered subject to this license unless specified otherwise within
and may be distributed under any desired license and/or
offered for sale or rental.
Any run-time library or run-time code section linked into the
output by a compiler or similar code-generating tool governed by this
license is considered to be an integral part of the output,
and its presence does not subject the generated work to this license either.
(This is, of course, assuming you are not using said tools to generate a
derivative work based on this package in violation of the other
However, if you are linking or including a separately distributed
library that is under this license,
no matter what tool you are using to do the linking or inclusion, you are then
considered to be making a derivative work based on that library
and your work does fall under
this license. To avoid this, do not include the library with your work (even
though it needs the library to function) and instead
offer the library separately without cost.
- In addition to non-commercial use and the uses permitted above,
you may use this software package in any for-profit endeavour as long as
it does not involve the specific sale or rental of this package.
Some specific but by no means exhaustive examples are
listed below. Note that some of these situations may require
additional action be taken to ensure compliance.
- If this package or a derivative work
allows you to serve data or make data available to others
(for example, web servers, mail servers, gopher servers, etc.), you may use
it to serve any commercial content or in any commercial setting
whether you choose to charge a fee or not, as
you are considered to be earning income from the content you serve and/or the
services facilitated by your business and not from
the sale of this package itself. (This is, of course, assuming that you are
not charging a fee for sale or rental of
this package or a derivative work based on this package
in violation of the other license terms.) Similarly, any data you may
acquire from the use of this package is yours, and not governed by this
license in any way even if for-profit.
- If you are selling a product that includes this package or a derivative
as part of your product's requirements for function or as a bundled extra,
such as an operating system distribution, you may charge a fee for your
product as long as you also make this package or said derivative work available
for free separately (such as by download or link back to this package's site),
as you are considered to be
requesting a fee for your own product and the package is merely
included as a convenience to your users.
- If you offer installation of this package or a derivative work
as a service,
you may charge a fee for the act of installation as long as you also make
this package or said derivative work
available for free (such as by download or link back
to this package's site), as you are considered to be requesting a fee for the
act of installation and not for the software you are installing.
- The Author may also grant, in writing, other specified exemptions for your
particular commercial purpose that do not contravene
the spirit of this license or any license terms this package additionally
- In your derivative works based on this package, you may choose to offer
warranty support or guarantees of performance. This does not in any way make
the original Author legally, financially or in any other respect liable for
claims issued under your warranty or guarantee, and you are solely
responsible for the fulfillment of your terms
even if the Author of the work you have
based your work upon offers his or her own.
- In your derivative works based on this package, you may further restrict
the acceptable uses of your package or situations in which it may be employed
as long as you clearly state that
your terms apply only to your derivative work and not to the original reference
distribution. However, you may not countermand or ignore, directly or
otherwise, any restriction already made
in the reference distribution's license, including in this document itself,
in similar fashion to other licenses allowing compatible licenses to co-govern
a particular package's use.
What you must not do under this license
Remember that these limits apply only to redistribution of a reference
distribution, or to a true derivative work. If your project
does not include this package or code based upon it, even if it requires
this package to function, it is
not considered subject to this license or these restrictions.
- You must not charge a fee for purchase or rental of
this package or any derivative work
based on this package. It is still possible to use this package in a
commercial environment, however -- see
What you are permitted to do under this license.
- You must not countermand or ignore, directly or otherwise, the
restrictions already extant in this package's license in your derivative
work based on it. As a corollary, you must not place your derivative work
under a secondary license or description of terms that conflicts
with it (for example, this license is not compatible with the GNU Public
- You must not label any modified distribution of this package as
a reference or otherwise official distribution without the permission of the
original Author or Authors. You must clearly specify that your modified work
is a derivative work, including binary-only releases if the original
included source code and you do not even if you did not modify the source
prior to compilation.
What you must do under this license
- You must agree to all terms specified (agreement to which is
unconditionally signified by your
usage, modification or repurposing of this package), or to remove the package
from your computer and not use it further.
- In the absence of any specific offer for redress or assistance
under warranty or
guarantee of performance that the Author of this package might make, you
must agree to accept any and all liability that may come from the
use of this package, proper or improper, real or imagined, and certify without
condition that you use this product at your own risk with no guarantee
of function, merchantability or fitness for a particular purpose. If such
offer of redress or assistance
is extended, it is fulfillable only by the Author who extended the offer,
which might not necessarily be this Author, nor might it be the Authors of
any packages it might be based upon.
- If you choose to publicly redistribute this package or create a
derivative work based on this package, you must make it available
without any purchase or rental fee of any kind.
- If you choose to create a derivative work based on this package,
your derivative work must be copyrighted,
and must be governed under
(at a minimum) the original package's license, which will necessarily include
all terms noted here.
As such, if you choose to distribute your derivative work,
you must include a human-readable license in your distribution
containing all restrictions of use, necessarily including this license, and
any additional restrictions the
Author has mandated that do not contravene this license which you and users
of your derivative work must also honour.
- If you choose to create and distribute
a derivative work based on this package,
your derivative work must clearly make reference to this package,
any other packages your work or the original work might be based on,
and all applicable copyrights, either in your
documentation, your work's standard human-readable output, or both. A suggested
method might be
