[tex-live] Updates to the TeXLive infra structure

[Norbert Preining]

Hi Florent, hi all,

I have updated the perl modules and the specification in the pod
documentation such that:

> 	docfiles size=.... 
> 	 file1 attr1="val1" attr2="val2" ...
> attrI is not allowed to contain spaces, valI can contain spaces, but no `"'

is allowed. Note that for now the ONLY attributes are
	language
	details

Furthermore, there is the possibility to update practically everything
present in the Catalogue (and which is already parsed in
TeXCatalogue.pm) into a TLPOBJ by using
	catalogue-foobar value
as key/value pair. These things are available via
	$tlpobj->cataloguedata->{'foobar'}

I also wrote a method for TLPOBJ
	update_from_catalogue($texcatalogueobject)
which does currently the following:
	add
		catalogue-version
		catalogue-license
		catalogue-url
	(respective fields in the xml files in the Catalogue)
and for docfiles adds the 
	details="..."
and
	language="..."
tags if present in the catalogue.

The logic behind this is the following (in pseudocode):

for each CatalogueDocFile
  take the href entry
  remove the 'ctan:' prefix
  remove the ctan path element 
  # what remains is eg /README or /doc/foobar.pdf
  for each TLPOBJ Docfile
    if it matches /CatalogueDocFile$/ # ie end match
       update the detail and language stuff if present
    fi
  done
done


Since I don't know how the package tags will be named in the catalogue,
I haven't added the update of this, but if it is necessary, it is a
trivial change in TLPOBJ.pm, in update_from_catalogue, and in
TeXCatalogue.pm (less trivial, needs to be xml parsed).


I hope that brings us a step further ...

For Karl: Nothing changes for normal usage, since update-tlpdb does NOT
call tlpsrc2tlpdb with the catalogue stuff.

For Reinhard: If you still not use the modules take care ...

Best wishes

Norbert
