All the numerical options, if not specified otherwise, accept in input

a string representing a number, which may contain one of the

International System number postfixes, for example 'K', 'M', 'G'.

If 'i' is appended after the postfix, powers of 2 are used instead of

powers of 10. The 'B' postfix multiplies the value for 8, and can be

appended after another postfix or used alone. This allows using for

example 'KB', 'MiB', 'G' and 'B' as postfix.

Options which do not take arguments are boolean options, and set the

corresponding value to true. They can be set to false by prefixing

with "no" the option name, for example using "-nofoo" in the

commandline will set to false the boolean option with name "foo".
