Sorrowly, for the first time it is not possible for me to use if offline
since a couple of class links are not local links but links to root, e.g.
TString: root.cern.ch/root/html/TString.html
TStyle: root.cern.ch/root/html/TStyle.html
TDictionary, TDirectory, and many others.
It would be great if I could download a corrected version.
Meanwhile I had time to check the files for the html docs:
I am attaching the file ClassIndex.html as text file for version 0502 and 0504.
As you can see, ClassIndex_0504.txt contains many references href to root,
see e.g. all TArrayX classes with the exception of TArray itself.
This is not the case for ClassIndex_0502.txt.
I have just found that html506.tar.gz has still some problems seen earlier:
1, ClassIndex.html contains still some references href to root, see e.g. Event, Track.
2, It seems that some references within a class also point to the root website,
e.g. TFile.html: href to TArrayC, TUrl, TList point to the root website.
