Package differences - bla_all.deb vs. bla.deb

[Hugo van der Merwe <hugo@mailroom.com>]

What is the difference between the

  locales_2.1.2-5_all.deb

package file and the

  locales_2.1.2-5.deb

package file? I assume packages with a _i386 "extention" are specifically
for the i386 architecture. That makes me think the _all package is for all
architectures, but then what is the package without any "extention" for?

Is there some place where I can see this kind of thing? I didn't notice it
in the debian-policy documents. Maybe I didn't look in the right place? I
would prefer a pointer to where I can get this information, so that I can
easily get the complete information. I will not mind a direct answer
though.

Thanks for the list's eagerness to help,
