to pypaper.sty.
Added the use of the "avant" package to use AvantGarde for the sans-serif
font instead of the helvetica font loaded by the "times" package.
This is separated so I can build A4 and US Letter sizes without having to
edit files.
Anyone who downloads the source package can also simply edit this file,
which is a lot shorter than the manual.cls file, and easier to find the
appropriate line.
