# 1. Create a folder daca2 in your HOME folder
# 2. Put cppcheck-O2 in daca2. It should be built with all optimisations.
# 3. Optional: Put a file called "suppressions.txt" in the daca2 folder.
# 4. Optional: tweak FTPSERVER and FTPPATH in this script below.
# 5. Run the daca2 script: python daca2.py FOLDER
