php-geshi binary package in Ubuntu Xenial amd64

 GeSHi aims to be a simple but powerful highlighting class,
 with the following goals:
 .
    * Support for a wide range of popular languages
    * Easy to add a new language for highlighting
    * Highly customisable output formats
 .
 GeSHi aims to do this all as quickly as possible. Many customisable
 features of GeSHi facilitate speed increases, and you can easily find
 a balance between the amount of highlighting done and the speed in
 which it is done.
