anchor.diff:  === Generating a Configuration
   Generate a configuration with the following command:
   
  -****
  -$ `osc process -f _<filename>_`
  -****
  +----
  +$ osc process -f <filename>
  +----
   
   Alternatively, you can create from a template without uploading it to the
   template library by processing the template and creating from the same template
   by piping both commands:
   
  -****
  -$ `osc process -f _<filename.json>_ | osc create -f -`
  -****
  +----
  +$ osc process -f <filename.json> | osc create -f -
  +----
   
   You can override any link:../dev_guide/templates.html#parameters[parameters]
  -defined in the JSON file by adding the `-v` option and any desired parameters.
  -Note that the usage of the parameters is not restricted to only environment
  -variables. You can use the parameter reference in any text field inside the
  -template items.
  +defined in the JSON file by adding the `-v` option followed by a
  +comma-separated list of _<name>_=_<value>_ pairs.
  +A parameter reference may appear in any text field inside the template items.
   
   For example, you can override the *`ADMIN_USERNAME`* and *`MYSQL_DATABASE`*
   parameters to create a configuration with customized environment variables:
