`retawq` is an interactive, multi-threaded network client (web browser) for text terminals on computers with Unix-like operating systems. It is written in C, fast, small, nicely configurable, and comfortable; e.g. the low-level network communications are performed in a non-blocking way, and you can keep open as many "virtual windows" as you want and work simultaneously in two of them in a split-screen mode. In SliTaz the "man" command uses it to browse online manpages.
