### Brief System Overview

The top-level scripts and utility scripts should be fairly well-documented. Here
is a brief explanation of how they tie together:

1.  `envs/*` are lists of variables made with bash syntax. A user must set a
    `TFCI` env param pointing to a list of `env` files.
2.  `utilities/setup.sh`, initialized by all top-level scripts, reads and sets
    values from those `TFCI` paths.

# Apache Lucene and Solr have separate repositories now!

Solr has become a top-level Apache project and main line 
development for Lucene and Solr is happening in each 
project's git repository now:

- Lucene: <https://gitbox.apache.org/repos/asf/lucene.git>
