File extension MF description:
METAFONT is the dark but indispensable brother of TEX, the well known typesetting program written by Donald E. Knuth. Where TEX (most often through its son LATEX) works in the light, putting your words together in beautifully typeset documents, fully justified, with automatically generated tables of contents (and so many other features), METAFONT works in the shadows, doing the dirty work of generating the fonts your documents are typeset with, and without which you wouldn’t get anything but empty pages..mf
