* Package may be copied, such that the Copyright Holder maintains some         *
* semblance of artistic control over the development of the package,           *

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

*   "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.                                *

*   "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.                                                                  *
*                                                                              *
