\ProvidesFile{sphinxlatexcontainers.sty}[2021/05/03 containers]

% The purpose of this file is to provide a dummy environment sphinxclass which
% will be inserted for each class in each container directive. The class name
% will be passed as the argument to the environment. 
%
% For a class foo, the user can define customised handling of that class by
% defining the sphinxclassfoo LaTeX environment.

    \def\sphinxClassFunctionName{sphinxclass#1}%
    \ltx@ifundefined{\sphinxClassFunctionName}%
        {}% undefined so do nothing
        {\expandafter\begin\expandafter{\sphinxClassFunctionName}}%
