I think horrible is too hard a word. There are a *lot* of very nice  
things that has been produced. But now that I am actually trying to  
use it I run into stuff.

Here is another one: depends in a TLPOBJ are of the form "Package/ 
foo" or "TLCore/bar". To use that name to get the actual TLPOBJ I  
need to strip the first part.

                 $tlpkgname =~ s/^(Package|TLCore|Documentation| 
		my $tlpkg = $tlpdb->get_package( $tlpkgname);

I am throwing stuff away but without any ill effect. I do not need it.

What this implies is that we do not have a clear idea about the name  
space it is a mix of assumptions. E.g. is tlpkg name is unique, we do  
not need categories. But if it isn't, then the interface to get a  
package from a db should include category.

I don't care either way, we could have
- object name unique TL-wide, directory information in the list of  
files, no directory-implication in the categories, depends on the  
basis of name
- object name in combination with category unique (category stands  
for a directory like texmf, texmf-doc, etc.), file list without  
subdirectory information, depends on the basis of category and name

As it is now, there is a bit of both assumptions in the setup.

As there is above all redundancy, I guess it will work as is. But  
maintaining it will be more work than with a clean structure.
