sagemath_objects: Sage objects, elements, parents, categories, coercion, metaclasses
====================================================================================================================================


The pip-installable distribution package ``passagemath-objects`` is a
distribution of a small part of the Sage Library.

It provides a small, fundamental subset of the modules of the Sage library
("sagelib", ``passagemath-standard``), making Sage objects, the element/parent
framework, categories, the coercion system and the related metaclasses
available.


Dependencies
------------

When building from source, development packages of ``gmp``, ``mpfr``, and ``mpc`` are needed.
