The file fonttext.cfg can contain declarations relating to the use
of fonts in text modes.
If it exists, it defines which font shapes, families and encodings are
normally used in text mode, as well as the behavior of font attribute
commands such as \textbf etc.
It could be used, for example, to produce a LATEX format that, by
default, typesets documents using Times fonts. Be warned, however,
that such customisation can have unfortunate consequences; so please
read carefully this section and the file fontdef.dtx below if you
are thinking of doing this.
Please note carefully the above warning.
