@nishanths, thanks for you review, I've made some updates to address your requested changes. I hope it looks good now :)

[nishanths]

Thank you for the changes.

I see two build errors at the moment on the branch. Could you fix them, please?

% go build
# github.com/nishanths/license/v5
./license.go:36:10: undefined: apppend
./license.go:47:11: assignment mismatch: 2 variables but 1 values

And my apologies for not having an automatic CI check present. I will set that up for this repository after we merge this PR.

No worries, I'll have that fixed up in a second.

That was actually going to be my next contribution, if you want I can set this up.
