Description

Pyrex is a language for writing Python extension classes that may run at C speed. Pyrex is used in SAGE to interface external libraries and to implement time-critical components.

Notes

The version of Pyrex shipped with SAGE is patched to allow cimports across directory borders. These patches have not been accepted upstream so for the time being SAGE doesn't compile with a vanilla Pyrex.
