# Donate CPU
#
# A script a user can run to donate CPU to cppcheck project
#
# Syntax: donate-cpu.py [-jN] [--package=url] [--stop-time=HH:MM] [--work-path=path]
# -jN Use N threads in compilation/analysis. Default is 1.
# --package=url Check a specific package and then stop. Can be useful if you want to reproduce some warning/crash/exception/etc..
# --stop-time=HH:MM Stop analysis when time has passed. Default is that you must terminate the script.
# --work-path=path Work folder path. Default path is cppcheck-donate-cpu-workfolder in your home folder.
#
# What this script does:
# 1. Check requirements
# 2. Pull & compile Cppcheck
# 3. Select a package
# 4. Download package
# 5. Analyze source code
# 6. Upload results
# 7. Repeat from step 2
#
# Quick start: just run this script without any arguments
