Introduction

Assuming you correctly carried out the installation instructions in the Read-Me file supplied with , you should have a folder that looks something like this: to 2.8in

Here's a brief description of what's inside all those folders:

The TeX-inputs folder contains a large number of TEX input files stored in various subfolders. TEX looks in these subfolders if it can't find a given file in your current folder. The supplied subfolders contain the files needed to use Plain TEX, L^ATEX and REVTEX. If you have your own library of macro files then the best place for them is in a new subfolder in TeX-inputs.
The TeX-formats folder contains the format files read by TEX and the TeX.pool file read by INITEX. The three most popular formats are supplied: Plain.fmt, LaTeX.fmt and AMSTeX.fmt. Section $[*]$ describes how to create format files.
The TeX-fonts folder contains many TEX font metric files stored in various subfolders. These TFM files are required by TEX to carry out typesetting; see section $[*]$ .
The VF-files folder contains virtual font files; see section $[*]$ .
The PS-files folder contains various PostScript files. It also contains encoding files in the Encodings subfolder; see section $[*]$ .
The PK-files folder contains PK font files stored in various subfolders. The name of each subfolder indicates the ``size'' of the PK files kept within it; see section $[*]$ for how this size is calculated and for more information about PK files. is distributed with a fairly small set of PK files (sufficient to print out the documentation on most printers). New PK files at any desired size can be built on demand; see section $[*]$ .
The Configs folder contains 's configuration files. The most important of these is the Default file loaded by when it starts up. See section $[*]$ for a detailed discussion of configuration files, including the required syntax.
The Metafont folder contains files needed by , a Mac implementation of Donald Knuth's ${\logo METAFONT\null}$ program and other font related tools. The Default config file loaded by is in the Configs subfolder in Metafont. See section $[*]$ for more information about .
The MetaPost folder contains files needed by , a Mac implementation of John Hobby's MetaPost program. The Default config file loaded by is in the Configs subfolder in MetaPost. See section $[*]$ for more information about .
The DVIPS folder contains files needed by dvips, Tom Rokicki's popular DVI-to-PostScript translator. The application contains an enhanced version of dvips. See section $[*]$ for more information.
The TeX-docs folder contains examples of Plain TEX files, including nasty.tex which is used in the guided tour of . It also contains gentle.tex, the source file for Michael Doob's A Gentle Introduction to TEX. TEX beginners should find this a useful companion to The TEXbook by Donald Knuth.
The LaTeX-docs folder contains ozuser.tex, the source file for this user guide, plus hyper.tex which shows how to use the hyperref and color packages. Also provided in LaTeX-docs is the LaTeX Short Course subfolder generously donated by George Grätzer; it contains the source files for Part I of his book Math into L^ATEX — An Introduction to L^ATEX and AMS-L^ATEX.
The Help-files folder contains a number of text files used by . The information in these files can be displayed by selecting their names from 's Help menu. (Note that the help files for and are stored in the Help subfolders in Metafont and MetaPost respectively.)
The AMS folder contains all the input files for AMS-TEX and AMS-L^ATEX. It also contains TFM files and ${\logo METAFONT\null}$ source files for the AMS fonts.
The AlphaLite folder contains Pete Keleher's AlphaLite application for editing TEX/L^ATEX input files. Note that AlphaLite is shareware and comes with its own Register application. If you prefer to use a different editor then throw away the AlphaLite folder.
The BibTeX folder contains Vince Darley's port of BibTEX which can be used in conjunction with L^ATEX to generate a bibliography from information stored in a bibliographic database.
The MakeIndex folder contains Rick Zaccone's port of MakeIndex for creating a sorted index.
The Excalibur folder contains Excalibur, a spelling checker written by Rick Zaccone and Robert Gottshall. Excalibur was designed to handle L^ATEX documents, but also works quite well with Plain TEX files.
The Register folder contains the Register application for paying 's shareware fee. Some brief notes on how to use Register are also included.

The folder can be called anything you like, and can be moved anywhere on your disk. However, if you decide to rename some of the above folders or applications then you'll probably need to make corresponding changes to the various Default configuration files loaded by //. The paths to these Default files are stored as resource strings in the preferences file for each application, so you'll also need to use ResEdit if you want to change the names of the Configs, Metafont or MetaPost folders. If you are new to then my advice is to stick to the given folder names!
