Humanzip is a compression program that operates on text files. Unlike most compression algorithms, its output is human readable. Indeed, it is explictly meant to be read by humans and might even be easier to read than the original.
This application compresses files by looking for common strings of words and replacing them with single symbols. The idea is to reduce the screen and print size of documents. humanzip does not explictly try to reduce the size of the file as measured in bytes, although this usually happens incidentally.
There is no configure script. I assume that you have a modern GNU/Linux (or similar) system that has the usual libraries and so forth. Nothing unusual is required, just a C++ complier (g++, probably). If you want to change the install location, edit the very simple Makefile.
To compile, say "make".
To install, say "make install".
To uninstall, say "make uninstall".
