Hi everyone,

== Brief summary of this project ==

This project is a continuation of last year's project, "Automatically generated
overlay of R packages". Its aims are extending overlay creation and, more
importantly, automated overlay maintenance.

For reference, the roverlay git repo can be found at [0], which also provides
some documentation [1].


== Last week's progress ==

* completed SLOT handling. The slot value is configurable now ("take up to
<N> 'parts' from the calculated version", "use fixed value").
* started with validation of selfdeps (=dependencies on packages provided
by the overlay). The objective here is to eliminate packages ("future
ebuilds") that depend on uncreatable packages/ebuilds, while differentiating
between mandatory (=> "ebuild uncreatable") and optional (=> simply drop)
selfdeps. To achieve this, ebuild creation (for a single package) is paused
until other packages have been processed, and then resumed. This feature is
mostly done; documentation is todo.

Misc:
* added a test suite for dependency resolution
-> wrote an interface to access dependency resolution (independently of
overlay creation)
* added a hook that automatically creates the metadata cache after overlay
creation (suggested by heroxbd)


== Plans for this week ==

* proceed with selfdep validation
* improve ebuild quality further
