Configuration requiring logic is expressed in executable templates.
An executable template is a script which accepts parameters via environment variables or standard in, and writes a config file to standard out.
An executable template is a script which accepts configuration as a json string on standard in, and writes a config file to standard out.
The script should exit non-zero if it encounters a problem, so that cornfig knows what's up.
The output of the script will be written to the path corresponding to the executable template's path in the template tree.
e.g.
```bash
#/bin/sh
echo "[sql]"
echo "connection = mysql://$keystone_database_user:$keystone_database_password@$keystone_database_user/keystone"
```
TODO: the script is passed the contents of the metadata file on stdin, so you can use a higher-level languages, too:
```ruby
#!/usr/bin/env ruby
require 'json'
