            The Liberation Fonts are intended to be replacements for the three most
            commonly used fonts on Microsoft systems: Times New Roman, Arial, and
            Courier New. Since 2012 they are based on croscore fonts.

            There are three sets: Sans (a substitute for Arial, Albany, Helvetica,
            Nimbus Sans L, and Bitstream Vera Sans), Serif (a substitute for Times
            New Roman, Thorndale, Nimbus Roman, and Bitstream Vera Serif) and Mono
            (a substitute for Courier New, Cumberland, Courier, Nimbus Mono L, and
            Bitstream Vera Sans Mono).
