If the low level commands are deprecated, then what should one
use in plain pdftex? I can get optical alignment AKA protruding
characters to work with statements like;

\rm
\pdfprotrudechars=2
\input protcode.tex
\setprotcode\font

I use 
pdfeTeX 3.141592-1.21a-2.2 (Web2C 7.5.4)
kpathsea version 3.5.4

If there is a better way to do either character protrusion or
expanded characters what document should I consult? I use
the Pdftex User Manual Rev. 1.595 dated April 22, 2005 and the
Han The Thanh dissertation dated October 2000. Obviously I slept
through some important change on the expansion side (which I
could never get working.) So wake me up and point me to the
current gospel, please.
