%description
This package provides build-stage rpm automation to simplify the creation of Go
language (golang) packages.

It does not need to be included in the default build root: go-srpm-macros will
pull it in for Go packages only.

%description -n go-srpm-macros
This package provides SRPM-stage rpm automation to simplify the creation of Go
language (golang) packages.

It limits itself to the automation subset required to create Go SRPM packages
and needs to be included in the default build root.

The rest of the automation is provided by the go-rpm-macros package, that
go-srpm-macros will pull in for Go packages only.
