 `@synindex'
 -----------
 
   The `@synindex' command is nearly the same as the `@syncodeindex'
 command, except that it does not put the `from' index  entries into the
 `@code' font; rather it puts them in the roman font.  Thus, you use
 `@synindex' when you merge a concept index into a function index.
