`@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.

index at the end of a book or creating an index menu in an Info file.
