+sage_conf: Configuration module for the SageMath library (relocatable binary version)
+=====================================================================================
+
+Description
+-----------
+
+This package provides:
+
+- a single Python module, ``sage_conf``, providing configuration information
+  to the SageMath library at the time of its installation and at its runtime
+
+- a console script ``sage-config``, for querying the variables of ``sage_conf``
+  from the shell
+
+- a sourcable shell script ``sage-env-config``, providing additional configuration
+  information in the form of environment variables
+
+This version of the package is suitable for shipping it with binary
+distributions of Sage.
+
+It implements a relocation mechanism that allows an unprivileged user
+to install the distribution in any location.
+
+The Sage distribution should be configured to use a
+build and installation tree (``SAGE_ROOT``, ``SAGE_LOCAL``) in a
+subdirectory of the directory ``/var/tmp/``, whose name is specific to
+the version of the distribution and the version of Python in use,
+such as ``/var/tmp/sage-9.3.beta7-cpython-39-darwin``.
+
+Importing ``sage_conf`` (or using the installed
+``sage-config`` script) makes sure that a symlink from the hardcoded
+``/var/tmp`` location to the actual persistent installation location
+is created.  As the relocated libraries and programs contain the
+hardcoded path ``SAGE_LOCAL`` in various ways (including as rpaths),
+this symlink is necessary for the prebuilt libraries and programs to
+work.
+
+``/var/tmp`` is a sticky directory on all Linux distributions
+following the Filesystem Hierarchy Standard, as well as on macOS and
+on Cygwin.  On multi-user systems, only one user can use a given
+version of the distribution; other installation schemes are recommended
+for systems with multiple Sage users.
