hsc binary package in Ubuntu Focal i386

 It can be used on any HTML file and creates a new HTML file as output. In the
 input file, you may use an extended syntax based on HTML, which allows for
 things like macros, conditionals, variables, expressions etc.
 .
 It is mainly intended for creating and maintaining larger HTML projects.
 As a commandline tool, it can be used together with `make', and a
 dependency generator is included.
 .
 Hsc is not a tool to make HTML easier for beginners; it's a tool
 to make HTML a bit less painful and brain-damaged for people who
 already know how to work with it.
