% \section{Introduction}
%
% This package provides customized theorem-like environments specifically designed for computer science documents. It offers a set of pre-defined theorem styles and environments to streamline the creation of theorems, definitions, remarks, and other common structures in computer science papers and documents.
%
% \section{Usage}
%
% Load the package with:
% \begin{verbatim}
% \usepackage{csthm}
% \end{verbatim}
%
% To use the package with cleveref support:
% \begin{verbatim}
% \usepackage[cleveref]{csthm}
% \end{verbatim}
%
% \section{Implementation}
%
%    \begin{macrocode}
%&lt;*package&gt;
% Package options
\newif\if@csthm@loadcleveref
\DeclareOption{cleveref}{\@csthm@loadclevereftrue}
\ProcessOptions\relax

% Required packages
\RequirePackage{amsmath}
\RequirePackage{amssymb}
\RequirePackage{amsthm}
\RequirePackage{enumitem}
\RequirePackage{thmtools}

% Conditionally load cleveref if the option is set and hyperref is loaded
\if@csthm@loadcleveref
\AtBeginDocument{%
	\@ifpackageloaded{hyperref}{%
		\RequirePackage{cleveref}
		}{%
		\PackageWarning{csthm}{The 'cleveref' option was set, but 'hyperref' is not loaded. Skipping 'cleveref' loading.}
	}%
