Re: Czech patterns in TeXlive2003

Ah ... i just found that out yesterday and had on my agenda to ask you to 
look into it. I have now adapted cont-usr.tex and commented:

% \definefilesynonym [lang-cz.pat]  [czhyph.tex]
% \definefilesynonym [lang-cz.pat]  [skhyph.tex]

maybe you can trigger on:

\contextversion

Thanks for taking care of it.

Hans
