 *    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.
 *
 *    "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 ftp.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) 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.
 *
 *        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.
 *
 *    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. C or perl subroutines supplied by you and linked into this Package
 *    shall not be considered part of this Package.
