% definition of the "\spnewtheorem" command.
%
% Usage:
%
% \spnewtheorem{env_nam}{caption}[within]{cap_font}{body_font}
% or \spnewtheorem{env_nam}[numbered_like]{caption}{cap_font}{body_font}
% or \spnewtheorem*{env_nam}{caption}{cap_font}{body_font}
%
% New is "cap_font" and "body_font". It stands for
% fontdefinition of the caption and the text itself.
%
% "\spnewtheorem*" gives a theorem without number.
%
% A defined spnewthoerem environment is used as described
% by Lamport.
