# run valgrind to check for memory leaks
# -v -v options add more verbose output
# --show-reachable=yes show reachable memory, but also shows it in the linked thread lib code
# --tool=memcheck use the memcheck tool, there are other tools too
# --leak-check=full show all info
# --show-reachable=yes show reachable memory
# --track-fds=yes show open file descriptors
# --trace-children=yes trace forked children
# --log-file=00valgrindlog.txt write to log file
# gml4gtk uses monly calloc() and free() to check in the log file
