#
# Simple script to generate times.log that contains timing information for the last 20 revisions
# Typically these commands shall be used to get times.txt:
# mkdir src
# cp lib/* src/ <- fill src/ with some source code
# tools/times.sh
# gcc -o tools/times tools/times.c
# tools/times
mkdir -p src
cp lib/* src/ # fill src/ with some source code
#NOTE: also try with some files other then from cppcheck!
git checkout -b old
# if "old" already exists for some reason, do NOT work on current branch but bail out
git checkout -b old || exit
make clean
git reset --hard HEAD > times.log
