The msys-termcap package provides the /etc/termcap file. /etc/termcap is a database which defines the capabilities of various terminals and terminal emulators. Certain programs use the /etc/termcap file to access various features of terminals (the bell, colors, and graphics, etc.). The associated libtermcap package provides runtime and development support libraries for the applications which use the database. Unless you develop MSYS applications, you probably only need the msys-termcap-bin package, which contains the /etc/termcap database, and the msys-libtermcap-dll package, which provides the runtime library.
