About this pip-installable distribution package
-----------------------------------------------
The pip-installable distribution package `sagemath-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", `sagemath-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.
