thanks for the updates; i have installed both, and tweaked the catalogue entries.
Users may view the package catalogue entries at http://www.tex.ac.uk/tex-archive/help/Catalogue/entries/expl3.html http://www.tex.ac.uk/tex-archive/help/Catalogue/entries/xpackages.html or they may browse the package directories at http://www.tex.ac.uk/tex-archive/macros/latex/contrib/expl3/ http://www.tex.ac.uk/tex-archive/macros/latex/contrib/xpackages/
The catalogue entries will change (somewhat) overnight tonight.
