+ * Termcap compatibility support
+ *
+ * If your OS integrator didn't install a terminfo database, you can call
+ * _nc_read_termcap_entry() to support reading and translating capabilities
+ * from the system termcap file.  This is a kludge; it will bulk up and slow
+ * down every program that uses ncurses, and translated termcap entries cannot
+ * use full terminfo capabilities.  Don't use it unless you absolutely have to;
+ * instead, get your system people to run tic(1) from root on the terminfo
+ * master included with ncurses to translate it into a terminfo database.
+ *
+ * If USE_GETCAP is enabled, we use what is effectively a copy of the 4.4BSD
+ * getcap code to fetch entries.  There are disadvantages to this; mainly that
+ * getcap(3) does its own resolution, meaning that entries read in in this way
+ * can't reference the terminfo tree.  The only thing it buys is faster startup
+ * time, getcap(3) is much faster than our tic parser.
