### Old LaTeX font references such as `\``tenrm`

LaTeX 2.09 defined a large set of commands for access to the fonts that it had built in to itself. For example, various flavours of `cmr` could be found as `\``fivrm`, `\``sixrm`, `\``sevrm`, `\``egtrm`, `\``ninrm`, `\``tenrm`, `\``elvrm`, `\``twlrm`, `\``frtnrm`, `\``svtnrm`, `\``twtyrm` and `\``twfvrm`. These commands were never documented, but certain packages nevertheless used them to achieve effects they needed.

Since the commands weren't public, they weren't included in LaTeX2e; to use the unconverted LaTeX 2.09 packages under LaTeX2e, you need also to include the rawfonts package (which is part of the LaTeX2e distribution).
