I don't have a lot of time, but I can get you started.
Puppet way:
1) Create a File resource that creates the config directory.
2) Run "facter" at the command line and look for the name of the variable that
tells how many processors the computer has. That variable will exist when the
catalog is compiled as a variable.
3) Use a template with File to create your config file.
Quicker way: (Not reccomended)
1) Copy that script to the computer using "File".
2) Run the script using Exec.
