Here's the same thing, for Bee: (bee.rubyforge.org)
rpm     alias --spec:bee --qf '\
\n - properties:\
\n   - Name: "%{Name:yaml}"\
\n   - Version: "%{Version:yaml}"\
\n   - Release: "%{Release:yaml}"\
\n - target: all\
\n   description: run all targets\
\n   depends: \[prep, build, install, clean\]\
\n - target: prep\
\n   script: %{Buildprep:yaml}\
\n - target: build\
\n   script: %{Buildbuild:yaml}\
\n - target: install\
\n   script: %{Buildinstall:yaml}\
\n - target: clean\
\n   script: %{Buildclean:yaml}\
\n' \
         --POPTdesc=$"display spec file as bee ruby"

It creates a build.yml file, that can be run with bee.

That is, the trivial rpm spec file:

Summary:   Test
Name:      test
Version:   1.0
Release:   1
License:   Public Domain
Group:     Development/Tools

Trivial test package

echo prep

echo build

echo install

echo clean


becomes the trivial bee build file:

  - properties:
    - Name: "test"
    - Version: "1.0"
    - Release: "1"

  - target: all
    description: run all targets
    depends: [prep, build, install, clean]

  - target: prep
    script: |-
       echo prep

  - target: build
    script: |-
       echo build

  - target: install
    script: |-

       echo install

  - target: clean
    script: |-
       /bin/rm -rf '/var/local/tmp/test-root'

With #{Name} and friends being all set...
