\033[4mInput File\033[0m
    The input file of this program is the Chrome history file. It is a simple
    SQLite3 file. It's usual name is 'History'.

\033[4mOutput Format\033[0m
    Four output formats are available. csv and json is what you expect to be.
    Classical is a format where fields are separated by a \\t and column is a
    format where every fields are displayed in columns. You can specify the
    format using the -f flags. Moreover, the delimiter can be change with -d
    flag.

\033[4mColumn Selection\033[0m
    To select which field to display, use the -c flag with the following options
        st : Start Time
        rb : Received Bytes
        tb : Total Bytes
        pt : Percent Received
        p : path
