 # Symbol Overlay

 Highlight symbols with overlays while providing a keymap for various 
operations about highlighted symbols.  It was originally inspired by the 
package `highlight-symbol`.  The fundamental difference is that in 
`symbol-overlay` every symbol is highlighted by the Emacs built-in function 
`overlay-put` rather than the `font-lock` mechanism used in `highlight-symbol`.
