Usage: crnormz [-fgtlh]
    -f, --ignore-file=               Ignore file from the checker
    -g, --ignore-function=           Ignore forbidden functions
    -t, --ignore-type=               Ignore errors of a specific type
    -l, --ignore-level=              Ignore errors of a specific level (Major, Minor or Info)

# Run the norminette
$ crnormz

# Run the norminette excludind all .o files
$ crnormz -f "*.o"

# Run the norminette without checking the forbidden functions (printf and scanf)
$ crnormz -g "printf,scanf"

# Run the norminette excluding all O1 rules
$ crnormz -t "O1"

# Run the norminette excluding all info level rules
$ crnormz -l "info"

# Sort files alphabetically
$ crnormz -s

# Run the norminette without text formatting
$ crnormz -r
