[tex-live] tl2rpm: TeX Live 2008 packages to rpm converter

[Karl Berry]

    The problem is that there is "depend xecyr.ARCH" in section related to
    xecyr in the texlive.tlpdb so there is no way for a dependency
    resolver to figure out the package is available solely for win32.

Sorry, I still don't exactly understand why it is a problem.  How about
simply inferring it from the fact that there is no xecyr.<arch> in tlpdb
for anything but w32?  That's what we do, I think.

In other words, given "depend xecyr.ARCH" in texlive.tlpdb, if there is
no package named "xecyr.i386-linux" (or whatever), then you just ignore it.

Oh, maybe there is another answer: I could move the xecyr .bat's into a
separate package, say xecyr-w32.  Then the xecyr package could say
"depend xecyr-w32.win32" and there would be the explicit clue that it is
for Windows only.

I could move pngtools into wintools to get rid of that special case, but
I guess it won't help unless xecyr gets solved.  (BTW, I was thinking of
another package when I said before that it should be removed; xecyr is
fine and should stay.)

Perhaps Norbert can be of more help here ... Norbert?

    Replacing it with "depend xecyr.win32" will solve it.

I guess in theory; in practice I don't think the current code has any
way to intuit such a thing when it's generating tlpdb.  It seems overly
complex to add all that for this one tiny case.

    The similar case is collection-wintools. It is for win32 arch
    exclusively but there is no way to find it out.

Aside from the above, it's not unreasonable to have a special case for
collection-wintools, since it is, well, special.  It is the only
collection not contained in any scheme and is magically installed (by
default) only on Windows.

I'll answer about default schemes separately.

Thanks,
