The third distribution in this part of the tour A is bab el, which provides L T X with multi-lingual E capabilities. 2 The Mfnfss Distribution The mfnfss distribution is something of a `collecting p oint' for les in the distribution that have not got anywhere else to go. 2.1 FontPackages A These packages provide L T X interfaces to some E publicly available fonts. They do not provide the fonts themselves, which are available from the fonts tree in the standard CTAN archives. pandora The `Pandora' family of fonts designed by Nazneen N. Billawala is an alternative to the standard `Computer Mo dern' fonts of Knuth. The family consists of a full range of text fonts, including sans-serif and slanted. oldgerm The old German fonts designed byYannis Haralamb ous. There are three styles of text font, Schwabacher, Fraktur and Gothic. The terms `Fraktur' and `Gothic' tend to b e used in- terchangeably by English sp eaking mathemati- cians such as the present author, but the fonts in this collection have clearly distinguishable styles. There is also a font of `initials', highly ornate upp ercase letters, suitable for use as the rst letter of a section. If you wish to use this in `drop caps' style you may also want to use one of the contributed packages available on CTAN suchasdrop,ordropping, that automate TUGb oat, Volume 18 1997, No. 1 49 the setting of a suitable paragraph shap e and Scheme are installed, then one could in principle 1 A inserting the initial letter at the correct size. switch to Times Roman in a L T X do cument by E simply sp ecifying \fontfamily{ptm}\selectfont. 2.2 T1 Enco ded `Concrete' Fonts Normally one would instead want to assign the new A Note: The following two les require the old release font to one of the `default' L T X families, Roman, E 1.1 of the dc fonts.
