thesis-umich
LaTeX template for AIAA papers
The most recent stable version is thesis-umich 0.8.0. You can either download the thesis-umich.cls file directly or download the ZIP, which also includes a complete example with all the required source files.
Instructions
There is no special installation process associated with thesis-umich because it is just a single file. Simply put the thesis-umich.cls file in a convenient location and tell LaTeX about it in the \documentclass command. Since LaTeX is capable of interpreting relative paths, so it's acceptable to use commands like this one.
\documentclass{../tex/thesis-umich}
A system that allows multiple LaTeX projects to reference the same thesis-umich.cls may be convenient, but realistically most people probably only have one thesis anyway.
