the library builds a pipeline as follows :

        inputs      libcudf                outputs

deb  | 
rpm  |                                       |
     | --------------> (algo) ----------->   |
db   |                                       |
     |
cudf |

this pipeline is build around the folowing components :

common contains input routines to read deb, cudf, db, etc

libcduf is the central - in memory - data structure

db contains the databases modules all sharing a single interface Sql

deb contains all the routines to parse debian related files.

algo contains a collection of algorithm to manipulated dependencies 

A non exaustive list includes:
- Depsolver : edos routines
- Defaultgraph : graph manipulation utilities
- Strondeps : strong dependencies algorithm
- Statistic : small world graph statisitics

applications contains a collection of applications build upon the library.
