+

+ equivalent <B>infocmp</B> for ncurses. In addition, he added a few new

+
+ <B>o</B> the <B>-e</B> option, to support <I>fallback</I> (compiled-in) terminal
+ descriptions
+
+ <B>o</B> the <B>-i</B> option, to help with analysis
+
+ Later, Thomas Dickey added the <B>-x</B> (user-defined capabilities) option,
+ and the <B>-E</B> option to support fallback entries with user-defined
+ capabilities.
