Tasks of the Debian Science Blend
Technically a Debian Pure Blend builds a set of metapackages and provides an overview about the packages which are included and which are on the todo list for further inclusion. Both pages are rendered from the information inside the tasks files in GIT.
There is a mailing list and an Salsa project which maintains a Git repository for several packages that are team maintained by the Debian Science team.
