$0 - A Go production build tool that adds git-repository information,
product version, build-timestamp etc. It supports cross-compilation,
static linking and generating protobuf output.
If needed, it uses the gogo-slick protobuf compiler [github.com/gogo/protobuf].
Build output is in bin/\$OS-\$CPU for a given OS, CPU combination.

# sigtool/sign - Ed25519 signature calculation and verification
This is a small library that makes it easier to create and serialize Ed25519 keys, and sign,
verify files using those keys. The library uses mmap(2) to read and process very large files.
The companion program [sigtool](https://git.rgst.io/homelab/sigtool/v3) uses this library.
The companion program [sigtool](https://github.com/opencoff/sigtool) uses this library.
