FLAGS:
        --autohide_time                        
            Automatically hides the time scale in graphs after being
            shown for a brief moment when zoomed in/out.  If time is
            disabled via --hide_time then this will have no effect.
            
    -b, --basic                                
            Hides graphs and uses a more basic look.  Design is largely
            inspired by htop's.
            
        --battery                              
            Shows the battery widget in default or basic mode. No effect on
            custom layouts.
            
    -S, --case_sensitive                       
            When searching for a process, enables case sensitivity by default.
            
    -c, --celsius                              
            Sets the temperature type to Celsius.  This is the default
            option.
            
        --color <COLOR SCHEME>                 
            Use a pre-defined color scheme.  Currently supported values are:
            
            +------------------------------------------------------------+
            | default                                                    |
            +------------------------------------------------------------+
            | default-light (default but for use with light backgrounds) |
            +------------------------------------------------------------+
            | gruvbox (a bright theme with 'retro groove' colors)        |
            +------------------------------------------------------------+
            | gruvbox-light (gruvbox but for use with light backgrounds) |
            +------------------------------------------------------------+
            | nord (an arctic, north-bluish color palette)               |
            +------------------------------------------------------------+
            | nord-light (nord but for use with light backgrounds)       |
            +------------------------------------------------------------+
            
            Defaults to "default".
    -C, --config <CONFIG PATH>                 
            Sets the location of the config file.  Expects a config
            file in the TOML format. If it doesn't exist, one is created.
            
    -u, --current_usage                        
            Sets process CPU% usage to be based on the current system CPU% usage
            rather than total CPU usage.
            
    -t, --default_time_value <MS>              
            Default time value for graphs in milliseconds.  The minimum
            time is 30s (30000), and the default is 60s (60000).
            
        --default_widget_count <INT>           
            Sets the n'th selected widget type to use as the default widget.
            Requires 'default_widget_type' to also be set, and defaults to 1.
            
            This reads from left to right, top to bottom.  For example, suppose
            we have a layout that looks like:
            +-------------------+-----------------------+
            |      CPU (1)      |        CPU (2)        |
            +---------+---------+-------------+---------+
            | Process | CPU (3) | Temperature | CPU (4) |
            +---------+---------+-------------+---------+
            
            And we set our default widget type to 'CPU'.  If we set
            '--default_widget_count 1', then it would use the CPU (1) as
            the default widget.  If we set '--default_widget_count 3', it would
            use CPU (3) as the default instead.
            
        --default_widget_type <WIDGET TYPE>    
            Sets which widget type to use as the default widget.
            For the default layout, this defaults to the 'process' widget.
            For a custom layout, it defaults to the first widget it sees.
            
            For example, suppose we have a layout that looks like:
            +-------------------+-----------------------+
            |      CPU (1)      |        CPU (2)        |
            +---------+---------+-------------+---------+
            | Process | CPU (3) | Temperature | CPU (4) |
            +---------+---------+-------------+---------+
            
            Setting '--default_widget_type Temp' will make the Temperature
            widget selected by default.
            
            Supported widget names:
            +--------------------------+

        --mem_as_value                         
            Defaults to showing process memory usage by value.  Otherwise,
            it defaults to showing it by percentage.
            
        --network_use_binary_prefix            
            Displays the network widget with binary prefixes (i.e. kibibits, mebibits) rather than a decimal prefix
            (i.e. kilobits, megabits).  Defaults to decimal prefixes.
