Why is amstex divided between tetex-base and tetex-extra?

[frank@kuesterei.ch (Frank Küster)]

Hi all,

I just noticed that amstex files are mainly in tetex-extra (and, of
course, tetex-doc), but there are some in tetex-base. There are some
empty directories, and the two files 

tetex-base: /usr/share/texmf/pdftex/amstex/config/pdfamstex.ini
tetex-base: /usr/share/texmf/pdftex/amstex/config/pdfbamstex.ini

whereas the corresponding tex files are in tetex-extra:

tetex-extra: /usr/share/texmf/tex/amstex/config/amsppt.sti
tetex-extra: /usr/share/texmf/tex/amstex/config/amstex.ini
tetex-extra: /usr/share/texmf/tex/amstex/config/bamstex.ini

Does anybody remember a specific reason for this? Or is it just an
accident, and the pattern in debian/rules should rather be "/amstex/",
not "/tex/amstex/"?

Regards, Frank
