#What does the first "-" mean at the beginning of the line in a Makefile ? 
#It means that make itself will ignore any error code from rm. 
#In a makefile, if any command fails then the make process itself discontinues 
#processing. By prefixing your commands with -, you notify make that it should 
#continue processing rules no matter the outcome of the command.

#mkdir -p, --parents no error if existing, make parent directories as needed
