First of all, I want to congratulate you for the amazing job you are doing.
I am the main developer of pgRouting, and the project is part of the OSGeo
Foundation [2] community projects.
pgRouting extends the PostGIS / PostgreSQL geospatial database to provide
geospatial routing functionality.
I would like pgRouting [1] to be added on the list of
"Boost Graph Library Users"
The Boost license is on the projects repository [3] and we document when a
boost graph function is used for example in [4]
