GOUTILS
|
|
|
|
This is a collection of small utility code I've written in Go; the `cmd/`
|
|
directory has a number of command-line utilities. Rather than keep all
|
|
of these in superfluous repositories of their own, or rewriting them
|
|
for each project, I'm putting them here.
|
|
|
|
The project can be built with the standard Go tooling, or it can be built
|
|
with Bazel.
