Terminal Handling
-----------------
Historically, several different libraries have provided the features the
shell needs to provide output to the terminal. The most common have been
termcap, which is now largely outmoded, and curses, which supersedes
termcap and typically contains the same features as well as others.
configure will search for an appropriate library; the default search order
is "tinfo termcap ncurses curses" except on HP-UX and Solaris where it is
"Hcurses ncurses curses termcap". Note that even though termcap is usually
searched first zsh tries to make features from curses available and if the
curses library contains both curses and termcap features, as is normal,
the curses variant is used. ncurses is a newer version of curses
and tinfo is related to it.
On some systems a suitable development package with a name such as
curses-devel or ncurses-devel needs to be installed before zsh can
be compiled. This is likely to be contained on any installation media,
or available for download. It is highly unlikely that you will need to
compile this from scratch.
You can tell configure which libraries to search by passing an
argument via --with-term-lib. This takes a space-separated list
of libraries to try as its argument, so the default is equivalent to
--with-term-lib="tinfo termcap ncurses curses". It replaces the
old option --with-curses-terminfo, which altered the search order but
didn't allow an explicit search list to be passed.

Since 4.2:
The configuration option --with-curses-terminfo has been replaced
by the option --with-term-lib="LIBS" where LIBS is a space-separated
list of libraries to search for termcap and curses features.
The option SH_WORD_SPLIT, used in Bourne/Korn/Posix shell compatibility
mode, has been made more like other shells in the case of substitutions of
