Yes, Martin, what would I do without you?
You are right, of course, there should be some distinction between the
static and the dynamic (automatically generated) index files.
I think we need to distinguish two things. On the one hand, we need
some short (a one-liner as in TITLE) and some long ``documentation'' on
a package. The long one could be sort of like the README files which
come with certain S add-ons (and typically list the user-level objects
in the pkg).
If we ask for information about a package, the long one is what we
should get, I think.
On the other hand, it is clearly useful to have lists of R objects and
data sets a package provides. These are the INDEX files. But these
could also be auto-generated upon installation from the man sources.
In fact, as we also need them in HTML (and maybe in LaTeX), there is
not too much use for prebuilt ones ...
So, what shall we do about the indices? As I already said, I think that
the documentation for data should be converted to the new Rd format and
merged with the R object documentation (same name space etc).
Clearly, we should have a list of data somewhere, so that we can quickly
list all data sets. Hmmm ... I guess I am not entirely sure what to do.
Library `info' should be o.k.: we create the LibIndex from a README
like file and the TITLE files of all packages in the lib.
For the time being, I will not change anything. (Unless we have a real
In the new dir structure, should the INDEX and TITLE files be installed
to $lib/$pkg or its help subdir? They make sense outside of help ...
