Re: Shed light on Tetex packages

That's right, but there should be not much harm.  See below.

No.  Apparently my message was not as clear as I thought it was.  You
always need tetex-bin and libkpathsea3.  In addition, you need a texmf
tree.  You can get one by installing tetex-tiny or tetex-base.
It doesn't matter too much, as this is taken care of automagically by

Yes.  The reason for this is that tetex is very big (have you looked
at the sizes of the packages?)  About every distribution of tetex
offers packaging in multiple parts.

Yes.  You want tetex, simply select the 'tetex' package: and done.

Yes, this is where it gets hairy.  As you may have noticed, I have
asked to remove these.  These packages took care of a smooth upgrade
from the previous tetex packaging to the new one.

For users it should 'just work'.  For developers: use the source,
dependencies are listed in the setup.hint files.

I don't understand this.

Anyway: tetex-tiny overlaps with tetex-base (and possibly
tetex-extra).  Ideally, this should be handled by alternative
'requires:' and 'conflicts:', but setup.exe doesn't do that, yet.

The trick is that only the selection of files in the packages is
changed, the files themselves are indentical.  Configuration issues
are taken care of during postinstall.  The only thing you should not
do, is install both, and then remove one of them.  If you want to do
that, you should re-install the remaining package (tetex-base or

Maybe tetex-tiny should simply be removed until setup can handle this,
and we should simple force the 15MB download upon everyone who uses
tex?  I was trying to be low-bandwith friendly.

You should be fine.

Yes, that's true.  Don't do that.

I'll add this note to the announce message, and include it in the
README for the next release:

    NOTE: The tetex-tiny and tetex-base packages overlap.  If you
          choose for a full tetex installation (or just install
          everything), both will be installed, which should be fine.
          Please don't uninstall one of them, there should be no need
          to do so.  If you do, you must reinstall the other.
