A license meant to facilitate software testing, without placing severe restrictions on use of the software except in terms of including original versions of the software.
The Open Group Test Suite License
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.
Testing is essential for proper development and maintenance of
For buyers: adequate conformance testing leads to reduced
integration costs and protection of investments in applications,
software and people.
For software developers: conformance testing of platforms and
middleware greatly reduces the cost of developing and maintaining
multi-platform application software.
For suppliers: In-depth testing increases customer satisfaction and
keeps development and support costs in check. API conformance is
highly measurable and suppliers who claim it must be able to
substantiate that claim.
As such, since these are benchmark measures of conformance, we feel
the integrity of test tools is of importance. In order to preserve
the integrity of the existing conformance modes of this test
package and to permit recipients of modified versions of this
package to run the original test modes, this license requires that
the original test modes be preserved.
If you find a bug in one of the standards mode test cases, please
let us know so we can feed this back into the original, and also
raise any specification issues with the appropriate bodies (for
example the POSIX committees).
"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.
"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
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 the following:
rename any non-standard executables and testcases so the
names do not conflict with standard executables and
testcases, which must also be provided, and provide a
separate manual page for each non-standard executable and
testcase that clearly documents how it differs from the
4. You may distribute the programs of this Package in object code
or executable form, provided that you do at least the following:
accompany any non-standard executables and testcases with
their corresponding Standard Version executables and
testcases, giving the non-standard executables and
testcases non-standard names, and clearly documenting the
differences in manual pages (or equivalent), together with
instructions on where to get the Standard Version.
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.
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 whomever
generated them, and may be sold commercially, and may be aggregated
with this Package.
7.Subroutines supplied by you and linked into this Package shall
