>Dear Juergen,

>I am attaching the file Sinaia.zip. It contains:

>1) The files of Kluwer.zip (the most recent version I could find).
>(In the original Kluwer.zip one finds an embedded zip file,
>kluwsrc.zip---for the class crckbked.cls one needs at least one
>file from it. Therefore I have unpacked everything.)

>The main documentation for the Kluwer style is useman.ps

>2) The files for camera ready copies for proceedings, starting

>3) Sinaia.tex in which I have tried to
>indicate the use of the Kluwer style.

>One issue is the choice of fonts. In Sinaia.tex I have activated

>Kluwer has developed its own macros for the author names, title of the 
>paper etc. This is perhaps the biggest difference to other styles like 
>AMS. On the other hand, it appears only once in the article, and it is no 
>problem to follow their instructions.
>
>There are 3 other notable differences to the AMS style:
>
>(i) The name for the environments for proofs is "pf" (or "pf*")
>and not "proof". ("pf" was used by the AMS in former versions of
>AMSLaTeX.) One can of course define an environment "proof" using
>"pf". I haven't done it (yet).

>(ii) It is not possible to create the right (in my opinion)
>environment for definitions, examples and remarks, since the
>"newtheorem" provided by Kluwer does not allow various
>"theoremstyle" options, for example, in order to use \rm as the
>main text font in such an item.
>
>Therefore one has to insert \rm in the right way in order to make
>the text upright. (Example included in Sinaia.tex)
>
>(iii) The AMSLaTeX macro package is NOT loaded automatically. Therefore 
>one has to do this explicitly if one wants to use the package. (I have not 
>included the package in Sinaia,tex.)
>
>The easiest solution for using these files is to create a special
>folder, unpack the zip file into it, and write the article there.
