Trilinos: to split or not to split?

[Nico Schlömer <nico.schloemer@gmail.com>]

Hi everyone,

Graham, Felix, and I are just looking into packaging Trilinos [1] for Debian (again [2]). The structure of Trilinos similar to boost in that it consists of a few dozen "packages".

We're now trying to figure out if it's best to ship all of Trilinos in one target (e.g., libtrilinos{-dev}) or to split it up along the packages (libtrilinos-{belos,amesos,ml,...}{-dev}). In the current version [3], we're doing the latter.

Some numbers:

```

$ ls libtrilinos-*12.2.1*.deb | wc -l
90
$ du -s libtrilinos-*12.2.1*.deb | cut -f1 -d' ' | sort -h | tail -n 10
912
924
1064
1096
1376
1568
1944
2644
2960
7596
$ for i in libtrilinos-*12.2.1*.deb; do dpkg -I $i | grep Installed-Size | \
  cut -d' ' -f3 ; done | sort -h | tail -n 10
4865
4913
5005
7171
7566
10682
12912
19051
20403
47295 # <= I guess, this means 47MB
```

Is there a Debian policy on this? What's your opinion?

Cheers,

Nico
