I rather mean write SQL code and put them into testable scripts into
Git.  At least this is my way to test the SQL code either by using files
ending up with *.SQL you could pipe into `psql udd` or you can also use
simple shell scripts.  I just created two such examples here:


The first script gis-thermometer.sh tries to reimplement the gathering
of data for the Debian GIS package thermometer[1] that could be
implemented for all Blends in a similar manner.  The second script
upgradable.sh tries to find all packages that can be upgraded to newer
upstream per Blend.

Simple scripts like this can be easily tested and verified whether they
deliver the data we need.  Once we have the data correct this can be
wrapped up into a Python script that will output the control file in
our case.

It rather contains the status of SVN (trunk).  This is what I was caring
for in the first place and this is from what we need to create the
metapackages from (which is equivalent to the creation process currently
which also uses trunk.

In you other mail you confirmed that this became clear to you.

Kind regards
