+/- Read and match the natspec documentation made for each function in the code above with its code, for each important function list the differences if they don't match perfectly.
+/- Make a list with function signatures and assessments for parts that do not match according to your interpretation.

 /- For large codebases it's ok to analyze only the most important functions (normally the external ones).
+/- You don't need to execute any part of the code, just read it.
