The problem by using this is that if I search for packages which contain a
specific library there may be more than one package which contains this
lib. E.g. on amd64 systems the library "libXext.so.6" is in "ia32-libs" and
"libxext6". If I use OR search, I cannot help choosing the right package
for one library. (For every lib specific criteria have to apply to mark the
package as "should-be-installed") Also I need to know, which library or
file is not provided by a package.
(This is essential to make binaries work on as much Linux distributions as
possible)
