README excerpt
Welcome to tmux!
tmux is a terminal multiplexer: it enables a number of terminals to be created,
accessed, and controlled from a single screen. tmux may be detached from a
screen and continue running in the background, then later reattached.
This release runs on OpenBSD, FreeBSD, NetBSD, Linux, macOS and Solaris.
* Dependencies
tmux depends on libevent 2.x, available from:
 https://github.com/libevent/libevent/releases/latest
It also depends on ncurses, available from:
 https://invisible-mirror.net/archives/ncurses/
To build tmux, a C compiler (for example gcc or clang), make, pkg-config and a
suitable yacc (yacc or bison) are needed.
* Installation
To build and install tmux from a release tarball, use:
 $ ./configure && make
 $ sudo make install
tmux can use the utempter library to update utmp(5), if it is installed - run
configure with --enable-utempter to enable this.
To get and build the latest from version control - note that this requires
autoconf, automake and pkg-config:
 $ git clone https://github.com/tmux/tmux.git
 $ cd tmux
 $ sh autogen.sh
 $ ./configure && make
 $ sudo make install
