This directory contains the results of compilation tests. Specifically,
the results are from testing both the from-scratch compilation time and
relative binary size increases of various features for both the `regex` and
`regex-automata` crates.

Here's an example of how to run these tests for just the `regex` crate. You'll
need the `regex-cli` command installed, which can be found in the `regex-cli`
directory in the root of this repository.

This must be run in the root of a checkout of this repository.

```
$ mkdir /tmp/regex-compile-test
$ regex-cli compile-test ./ /tmp/regex-compile-test | tee record/compile-test/2023-04-19_1.7.3.csv
```

You can then look at the results using a tool like [`xsv`][xsv]:

```
$ xsv table record/compile-test/2023-04-19_1.7.3.csv
```

Note that the relative binary size is computed by building a "baseline" hello
world program, and then subtracting that from the size of a binary that uses
the regex crate.
