Yeah, too bad.  I don't like kittens anyway.

Yeah, along those lines I also think.  Though I'd like to experiment with 
some more things put into .solv files, e.g. license and summary (certainly 
not description or, heaven forbid, changelog, though even for them I'd 
like to have some better on-disk form, at least chunk-wise compressed).  
At least all info "important" for solving should be in there, which also 
includes IMHO the category of patches and the like.

;-)  It actually compiles (against a libzypp svn from, hmm, friday I 
think), but you need changes to the CMakeLists.txt files for 
INCLUDE_DIRECTORIES and TARGET_LINK_LIBRARIES.

And then you need to create the .solv files by hand.  As root, do:

% cd /var/cache/zypp
% sqlite3 zypp.db 'select id,alias from repositories'
1|openSUSE-10.3-retail 10.3
28|openSUSE-10.3-Updates
29|http://ftp.gwdg.de/pub/linux/misc/packman/suse/10.2/

Now create 1.solv, 28.solv and 29.solv (for me) from the respective raw 
repodata in the raw/ subdirs:

% zcat /var/cache/zypp/raw/openSUSE-10.3-retail\ 10.3/suse/setup/descr/packages.gz | 
  susetags2solv > 1.solv
% ( echo "<patches>" ; cat raw/openSUSE-10.3-Updates/repodata/patch-*.xml; 
    echo "</patches>" ) | grep -v '<?xml' | 
  patchxml2solv > 28.solv
% zcat raw/http\:/ftp.gwdg.de/pub/linux/misc/packman/suse/10.2/repodata/primary.xml.gz |
  rpmmd2solv > 29.solv

The patchxml2solv needs a patch from me, and it's broken as the 
primary.xml.gz in that repo is not used.

Now zypper with libzypp on that patch will take up these .solv files 
instead of zypp.db.  And hence will probably break all over, but at least:

% time LD_LIBRARY_PATH=./zypp ../../zypper/build/src/zypper lu
