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 || 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 that use of this configuration file has the following consequences.
