Here is an alternative way for achieving the substitution. VTeX implements
an \aliasfont primitive. After
\aliasfont cmr10 = adobe-times
all references to cmr10 are replaced by adobe-times. This mechanism offers
two advantages over a text substitution file:
1) It's dynamic (\aliasfont settings can be saved in a .FMT file).
2) Versions of TeX that implement alterations can use \aliasfont to
map unneeded fonts. For example, in VTeX you can set
\aliasfont cmsl10 = cmr10 slant 233
and discard cmsl10 altogether.
This is true, but there is one giant disadvantage to adding \aliasfont
-- the result is no longer `TeX', since it's not 100% compatible.
It might be worth adding in concert with other new features, but not by
Also, an alias file still addresses the problem at the \font
name-filename level. This is somewhat different from \aliasfont's uses
(as stated above).
