Configpy is a Python tool designed to make reading configuration files quick and easy. It comes equipped with look-ahead and look-behind variable interpolation support, and also supports native types such as int, float, dict, and list to meet your configuration file parsing requirements.

Here is an example showcasing the capabilities of configpy:

```
from configpy import Config

cfg = """
nums = [1,2,3,4]
nando = "Nando"
names = ["Stevie", "${nando}", "Robbie"]
planets = { 'planet': '${red_planet}' }
red_planet = 'mars'
num_items = 5
item_cost = 1.99
"""

config = Config(cfg)

print sum(config.nums) # prints 10
print config.planets['planet'] # prints "mars"
config.names.sort()
print config.names # prints ["Nando", "Robbie", "Stevie"]
print config.num_items * config.item_cost # prints 9.95.
```

In summary, configpy is a great tool to streamline the process of reading and parsing configuration files. Its various features make it a versatile choice for a wide range of applications.
