# Simple script to generate times.log that contains timing information for the last <n> revisions
# Typically these commands shall be used to get times.txt:
mkdir -p src || exit 1
cp lib/* src/ || exit 2 # fill src/ with some source code
#NOTE: also try with some files other then from cppcheck!
# if "old" already exists for some reason, do NOT work on current branch but bail out
git checkout -b old || exit

# if build fails, make clean and try again
