Take a look at https://code.dlang.org/packages/dpq2
This is how packages work in D
To add dpq2 dependency to your project you need to execute the command:
```
dub add dpq2
```
it adds the last version of the dpq2 package. After this you are able to 
use this package in your project just import it in your source files.
