Preamble

The intent of this document is to state the conditions under which the Ada library may be copied, such that the Copyright Holder (see below) maintains some semblance of artistic control over its development, while giving Ada users the right to use and distribute the Ada library in a more-or-less customary fashion, plus the right to make reasonable modifications.

Definitions

"Library"

Refers to the collection of Ada source files distributed by the Copyright Holder, and derivatives of that collection of files created through textual modification.

"Standard Version"

Refers to such a library if it has not been modified, or has been modified as specified below.

"Copyright Holder"

Is whoever is named in the copyright or copyrights for the Ada library.

"You"

Is you, if you're thinking about copying or distributing this library.

"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.

Provisions:

  1. You may make and give away verbatim copies of the source form of the Standard Version of this Ada library 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 library modified in such a way shall still be considered the Standard Version.

  3. You may otherwise modify your copy of this Ada library 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:

    1. 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 The Public Ada Library, or by allowing the Copyright Holder to include your modifications in the Standard Version of the Ada library.
    2. Use the modified Ada library only within your corporation or organization.
    3. 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.
    4. Make other distribution arrangements with the Copyright Holder.

  4. You may distribute the programs of this Ada library in object code or executable form, provided that you do at least one of the following:

    1. 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.
    2. Accompany the distribution with the machine-readable source of the Ada library with your modifications.
    3. Accompany any non-standard executables with their corresponding Standard Version executables, giving the non-standard executables non-standard names, and clearly documenting the differences in manual pages (or equivalent), together with instructions on where to get the Standard Version.
    4. Make other distribution arrangements with the Copyright Holder.

  5. You may charge a reasonable copying fee for any distribution of this Ada library. You may charge any fee you choose for support of this Ada library. You may not charge a fee for this Ada library itself. However, you may distribute this Ada library in aggregate with other (possibly commercial) programs as part of a larger (possibly commercial) software distribution provided that you do not advertise this Ada library 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 Ada library do not automatically fall under the copyright of this Ada library, but belong to whomever generated them, and may be sold commercially, and may be aggregated with this Ada library.

  7. System-level subroutines supplied by you and linked into this Ada library in order to emulate the functionality defined by this Ada library shall not be considered part of this Ada library, but are the equivalent of input as in Paragraph 6, provided these subroutines do not change the library in any way that would cause it to fail the regression tests for the library.

  8. The name of the Copyright Holder may not be used to endorse or promote products derived from this software without specific prior written permission.

  9. THIS ADA LIBRARY 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.
