The option to define relative font sizes using the rscale parameter permits fine tuning
of font sizes. Fine tuning of the sizes x, xx, a, b, . . . as well as interline spacing is
handled by the bodyfont environment. This command normally takes two arguments,
but accepts an optional (first) one denoting a class. You can use this command to
tailor the environment for a specific typeface.
Although the default interline space is quite well tuned to the average font, you may want to change it
using this command. The defaults used to typeset this paragraph are related to the x--height of the font.

However, keep in mind that when you change the dimensions for one size, you also need to change them
for other sizes in order to get a consistent look and feel when switching to a smaller or larger size.
Math is kind of special in the sense that it has its own set of fonts, either or not related
to the main text font. By default, a change in style, for instance bold, is applied to text
only.
$ \sqrt{625} = 5\alpha$
$\bf \sqrt{625} = 5\alpha$
$ \sqrt{625} = \bf 5\alpha$
$\bfmath \sqrt{625} = 5\alpha$
The difference between these four lines is as follows:
√
625 = 5α
√
625 = 5α
√
625 = 5α
√
625 = 5α
In order to get a bold α symbol, we need to define bold math fonts. 2 The most convenient
way of doing this is the following:
2 Bold math is already prepared in the core modules, so normally one can do with less code
