used by packages that need curses. From curses.buildlink3.mk:
CURSES_DEFAULT
This value represents the type of curses we wish to use on the
system. Setting this to "curses" means that the system curses
implementation is fine.
Possible: curses, ncurses, pdcurses
+ Move all code to detect a built-in version of curses into a
curses.builtin.mk file.
+ Add code to {n,pd}curses/buildlink3.mk so make the headers and
libraries usable as <curses.h> and -lcurses if _PKG_USE_CURSES is
defined. _PKG_USE_CURSES is only defined by curses.buildlink3.mk.
+ Improve the detection of native ncurses in ncurses/builtin.mk and
allow headers and libraries to be usable as <ncurses.h> and -lncurses.
PDCurses is a public domain curses library that implements most of
the functions available in X/Open and System V R4 curses. This X11
port allows for recompiling programs using text-mode curses to produce
native X11 applications.
This package was originally created by <bjs> in pkgsrc-wip and with
several modifications by me to update to the latest version of PDCurses
and to be more buildlink-correct.
