 - modify cells wih regular expressions
 - reduce columns by specifying which columns to show, with regex support
 - color support

  SEPARATOR
    The option -s can be a single character, in which case the CSV parser
    will be invoked. You can also specify a string as separator. The string

    To make live easier, there are a couple of predefined regular
    expressions, which you can specify as classes:
        * :tab:
        Matches a tab and eats spaces around it.
        * :spaces:
        Matches 2 or more spaces.
        * :pipe:
        Matches a pipe character and eats spaces around it.
        * :default:
        Matches 2 or more spaces or tab. This is the default separator if
        none is specified.
