Walkthrough for Powertop
========================


First we create an osc package for this package.

Go to a suitable OBS directory with Mer_Core_i486 or similar as a repo target.

Now create the package:
  
  osc mkpac powertop
  cd powertop

Footnote: if you want to do it 'properly' you could do:

  osc meta pkg home:${ACC}:branches:Mer:Tools:Testing powertop -F - << EOF
  <package project="home:${ACC}:branches:Mer:Tools:Testing" name="powertop">
    <title>PowerTOP</title>
    <description>
  PowerTOP is a Linux tool to diagnose issues with power consumption and power management. In addition to being a diagnostic tool, PowerTOP also has an interactive mode where you can experiment with various power management settings for cases where the Linux distribution has not enabled those settings.

  </package>
  EOF

Now we're in a suitable osc directory we can setup git.

Find the upstream, clone and move the .git dir to the osc dir:

 git clone git://github.com/fenrus75/powertop.git
 mv powertop/.git .
 rm -rf powertop

What tag are we based on?

 git checkout -f v2.1.1
 gp_setup --pkg

In the future gp_setup --pkg=<tag> will do the git checkout <tag> next release

Edit yaml/spec/changes and create some packaging (we'll cheat and use philippe's):

 curl -kOL https://github.com/philippedeswert/powertop/raw/pkg-mer/powertop.changes
 curl -kOL https://github.com/philippedeswert/powertop/raw/pkg-mer/powertop.spec
 curl -kOL https://github.com/philippedeswert/powertop/raw/pkg-mer/powertop.yaml

Describe in the _src file how OBS gets the source (in this case, use simple git archive to make a tar.bz2 based on the tag v2.1.1)

 echo git:powertop-v2.1.1.tar.bz2:v2.1.1 > _src
 git add powertop.* _src

Check to ensure it builds:

 gp_mkpkg
 osc build Mer_Core_i486 i586

All good, commit:
 git commit -s
