src/ZConfig/NEWS.txt

+Changes since ZConfig 2.1:
+
+- More documentation has been written.
+
+- Added a timedelta datatype function; the input is the same as for
+  the time-interval datatype, but the resulting value is a
+  datetime.timedelta object.
+
+- Make sure keys specified as attributes of the <default> element are
+  converted by the appropriate key type, and are re-checked for
+  derived sections.
+
+- Refactored the ZConfig.components.logger schema components so that a
+  schema can import just one of the "eventlog" or "logger" sections if
+  desired.  This can be helpful to avoid naming conflicts.
+
+- Added a reopen() method to the logger factories.
+
+- Always use an absolute pathname when opening a FileHandler.
+
+- A fix to the logger 'format' key to allow the %(process)d expansion variable
+  that the logging package supports.
+
+- A new timedelta built-in datatype was added.  Similar to time-interval
+  except that it returns a datetime.timedelta object instead.
+
+Changes since ZConfig 2.0:
+
+- Removed compatibility with Python 2.1 and 2.2.
+
+- Schema components must really be in Python packages; the directory
+  search has been modified to perform an import to locate the package
+  rather than incorrectly implementing the search algorithm.
+
+- The default objects use for section values now provide a method
+  getSectionAttributes(); this returns a list of all the attributes of
+  the section object which store configuration-defined data (including
+  information derived from the schema).
+
+- Default information can now be included in a schema for <key
+  name="+"> and <multikey name="+"> by using <default key="...">.
+
+- More documentation has been added to discuss schema extension.
+
+- Support for a Unicode-free Python has been fixed.
+
+- Derived section types now inherit the datatype of the base type if
+  no datatype is identified explicitly.
+
+- Derived section types can now override the keytype instead of always
+  inheriting from their base type.
+
+- <import package='...'/> makes use of the current prefix if the
+  package name begins witha dot.
+
+- Added two standard datatypes:  dotted-name and dotted-suffix.
+
+- Added two standard schema components: ZConfig.components.basic and
+  ZConfig.components.logger.
+
+Changes since ZConfig 1.0:
+
+- Configurations can import additional schema components using a new
+  "%import" directive; this can be used to integrate 3rd-party
+  components into an application.
+
+- Schemas may be extended using a new "extends" attribute on the
+  <schema> element.
+
+- Better error messages when elements in a schema definition are
+  improperly nested.
+
+- The "zconfig" script can now simply verify that a schema definition
+  is valid, if that's all that's needed.

+        supports a hierarchical schema-driven configuration model that allows

+        ZConfig's model is very different from the model supported by the

+        ZConfig schema are written in an XML-based language and are able to

+        components are able to bind to conversion functions provided by Python
+        code in the package (or elsewhere), configuration objects can be
+        arbitrarily complex, with values that have been verified against
+        arbitrary constraints.  This makes it easy for applications to
+        separate configuration support from configuration loading even with

+This is ZConfig.
+
+ZConfig is a configuration library intended for general use.  It
+supports a hierarchical schema-driven configuration model that allows
+a schema to specify data conversion routines written in Python.
+ZConfig's model is very different from the model supported by the
+ConfigParser module found in Python's standard library, and is more
+suitable to configuration-intensive applications.
+
+ZConfig schema are written in an XML-based language and are able to
+"import" schema components provided by Python packages.  Since
+components are able to bind to conversion functions provided by Python
+code in the package (or elsewhere), configuration objects can be
+arbitrarily complex, with values that have been verified against
+arbitrary constraints.  This makes it easy for applications to
+separate configuration support from configuration loading even with
+configuration data being defined and consumed by a wide range of
+separate packages.
+
+ZConfig is licensed under the Zope Public License, version 2.1.  See
+the file LICENSE.txt in the distribution for the full license text.
+
+Reference documentation is available in the doc/ directory.
+
+Information on the latest released version of the ZConfig package is
+available at
+
+  http://www.zope.org/Members/fdrake/zconfig/
+
+You may either create an RPM and install this, or install directly from
+the source distribution.
+
+
+Creating RPMS:
+
+  python setup.py bdist_rpm
+
+  If you need to force the Python interpreter to, for example, python2:
+
+    python2 setup.py bdist_rpm --python=python2
+
+
+Installation from the source distribution:
+
+    python setup.py install
+
+  To install to a user's home-dir:
+    python setup.py install --home=<dir>
+
+  To install to another prefix (eg. /usr/local)
+    python setup.py install --prefix=/usr/local
+
+  If you need to force the python interpreter to e.g. python2:
+    python2 setup.py install

src/ZConfig/doc/README.txt

+The zconfig.tex document in this directory contains the reference
+documentation for the ZConfig package.  This documentation is written
+using the Python LaTeX styles.
+
+To format the documentation, get a copy of the Python documentation
+tools (the Doc/ directory from the Python sources), and create a
+symlink to the tools/mkhowto script from some convenient bin/
+directory.  You will need to have a fairly complete set of
+documentation tools installed on your platform; see
+
+    http://www.python.org/doc/current/doc/doc.html
+
+for more information on the tools.
+
+This documentation requires the latest version of the Python
+documentation tools from CVS.
