But this means for us that we MUST change our calculating and reporting
software
too which automatically produce lots of latex-files with \input{$HOME/...}.
Then we have 2 different versions of this software, one with $HOME and one
without.
It is often the case that we need to re-run an old calculation, then we would
have to return to an older tetex version as well!
Yes, it is very important that we use the same software-version to recalculate
as was used for the initial certification for one machine.
It would be better to have the latex relevant parts in our software UNCHANGED.
