+The Chemmacros package loads mathtools multiple times, but the subsequent loads lead to 
+problems with catcodes. I don't see a reason for this, but it happened. To prevent that
+we will stop loading of this file if mathtools is already loaded.
 
+It is possible that similar issues can happen with other early hooks configuration files.

 This should prevent compilation errors with commands declared using \''\DeclarePairedDelimiter' and MathML. 
 We need to patch the command at the moment when it is declared, so it must be available
 already in the preamble. This is why we use early hooks.
