-Non-Public-Domain Code Included With This Source Repository AS A Convenience
-----------------------------------------------------------------------------
-
-This repository contains a (relatively) small amount of non-public-domain
-code used to help implement the configuration and build logic.  In other
-words, there are some non-public-domain files used to implement:
-
-> ~~~
-./configure && make
-~~~
-
-In all cases, the non-public-domain files included with this
-repository have generous BSD-style licenses.  So anyone is free to
-use any of the code in this source repository for any purpose, though
-attribution may be required to reuse or republish the configure and
-build scripts.  None of the non-public-domain code ever actually reaches
-the build products, such as "sqlite3.c", however, so no attribution is
-required to use SQLite itself.  The non-public-domain code consists of
-scripts used to help compile SQLite.  The non-public-domain code is
-technically not part of SQLite.  The non-public-domain code is
-included in this repository as a convenience to developers, so that those
-who want to build SQLite do not need to go download a bunch of
-third-party build scripts in order to compile SQLite.
-
-Non-public-domain code included in this respository includes:
-
-  *  The ["autosetup"](http://msteveb.github.io/autosetup/) configuration
-     system that is contained (mostly) the autosetup/ directory, but also
-     includes the "./configure" script at the top-level of this archive.
-     Autosetup has a separate BSD-style license.  See the
-     [autosetup/LICENSE](http://msteveb.github.io/autosetup/license/)
-     for details.
-
-  *  There are BSD-style licenses on some of the configuration
-     software found in the legacy autoconf/ directory and its
-     subdirectories.
-
-The following unix shell command is can be run from the top-level
-of this source repository in order to remove all non-public-domain
-code:
-
-> ~~~
-rm -rf configure autosetup autoconf
-~~~
-
-If you unpack this source repository and then run the command above, what
-is left will be 100% public domain.
