## Binary Size
As of 2020-05-24, in early development, the relative binary sizes are:
121 MB default debug build
12 MB default release build
8.2 MB release build w/ LTO
6.6 MB release build w/ LTO, striped
After some small changes:
5.9 MB release build w/ LTO, size optimization, other flags
4.1 MB release build w/ LTO, size optimization, other flags, striped
Replacing reqwest with minreq:
6.3 MB release build w/ LTO, size optimization, other flags
4.1 MB release build w/ LTO, size optimization, other flags, striped
(so, not worth it, at least while using fatcat_openapi with hyper+tokio)
Note that release builds with LTO take *quite* a long time (many minutes). We
probably don't want that to be the default for `fatcatd` builds.

Low hanging fruit includes:
- reviewing features for reqwest, clap, regex, fatcat_openapi
- replace reqwest with something smaller
- use `ansi-term` (already part of clap)
- consider removing fancy clap features? meh
- look at graph; probably duplicate versions of things
