cmtty package specifies Computer Modern
Typewriter as the “typewriter style” font. It is useful when
using font packages that set the default monospace font to use
Computer Modern Typewriter (AKA CMTT) is a very readable monospace typeface that's good for setting code, program names, and other, similar, material. It is more compact than Courier, and thus allows you to have more material on a line than you would otherwise be able to have.
Using the Package
Simply add the line
to the preamble of your document.
cmtty.sty is used by the
department's HMC Clinic Report Class and thesis classes, so if you plan on using
these classes to work on such documents on your own TeX
system, you will also need this package.
