# 1. Create a folder daca2 in your HOME folder
# 2. Put cppcheck-O2 in daca2. It should be built with all optimisations.
# 3. Choose a folder to check. Choose any that match regexpr: (lib)?[0-9a-z]
# 4. Optional: Put a file called "suppressions.txt" in the daca2 folder.
# 5. Optional: tweak FTPSERVER and FTPPATH in this script below.
# 6. Run the daca2 script: python daca2.py FOLDER
