About this pip-installable distribution package
-----------------------------------------------

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

It provides a small subset of the modules of the Sage library
("sagelib", `sagemath-standard`) that is a superset of `sagemath-objects`
(providing Sage objects, the element/parent framework, categories, the coercion
system and the related metaclasses), making various additional categories
available without introducing dependencies on additional mathematical
libraries.


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

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