The `chet` package provides a streamlined LaTeX2e setup inspired by Paul
Ginsparg's `harvmac`. It gives papers the typographic look and feel of
`harvmac` while using standard LaTeX2e commands and environments.

**Author:** Andreas Stergiou (<andstergiou@gmail.com>)

See [doc/chetdoc.pdf](doc/chetdoc.pdf) for full documentation and examples.
