Yes, fontspec does have that.  But I don't want to specify the bold etc. 
using fontspec explicitly, I want to specify that Charis SIL is the main 
font using \setmainfont--and in this case, where the font files are 
located--and have it find regular, bold etc. styles.  AFAICT, while 
\setmainfont and \fontspec take the same parameters, I can't use 
\setmainfont to tell it where the four individual Charis SIL font files 
are located.  Unless I'm missing something.
