"""Modifies Cargo.toml to use an absolute rather than a relative path
The current implementation of PEP 517 in pip always does builds in an
isolated temporary directory. This causes problems with the build, because
Cargo.toml necessarily refers to the current version of pyo3 by a relative
path.
Since these sdists are never meant to be used for anything other than
tox / pip installs, at sdist build time, we will modify the Cargo.toml
in the sdist archive to include an *absolute* path to pyo3.
