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

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

%package     -n gomod-srpm-macros
Summary:        Source-stage rpm automation for Go modular packages
BuildArch:      noarch
Requires:       redhat-rpm-config >= 293
# macros.forge and forge.lua were split into a separate package.
# redhat-rpm-config pulls in forge-srpm-macros but better to explicitly Require
# it.

%description -n gomod-srpm-macros
This package provides SRPM-stage rpm automation to simplify the creation of Go
language (Golang) modular 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 gomod-rpm-macros package, that
gomod-srpm-macros will pull in for Go packages only.
