I can get that to work for the regular Charis SIL font.  But since the 
regular, bold, italic, and bold italic are each in their own files, it's 
not apparent to me how to get all four as styles of the main font using 
the "external fonts" syntax, since each filename is different.  That is, 
I can do
   \setmainfont[ExternalLocation=/foo/bar/]{CharisSILR.ttf
for the regular style font (the 'R' in the filename), but then I don't 
have the italic etc. versions.  And if I issue similar \setmainfont cmds 
for the other styles, I end up with the main font being available only 
in whatever style the last \setmainfont refers to.

Whereas \setmainfont finds all the styles if I use the font display 
name, since the display name for all four styles is the same ("Charis 
SIL"); it just doesn't find the right external location.

Or am I missing something about the syntax of this external location system?

Anyway, I guess the right way to fix this is to get rid of the old 
versions of the font (tomorrow).  Then I can use the display name 
syntax, and get all four styles of the newest version of the font (and 
the small caps).
