+ *	captoinfo.c --- conversion between termcap and terminfo formats
+ *
+ *	The captoinfo() code was swiped from Ross Ridge's mytinfo package,
+ *	adapted to fit ncurses by Eric S. Raymond <esr@snark.thyrsus.com>.
+ *
+ *	There is just one entry point:
+ *
+ *	char *_nc_captoinfo(n, s, parameterized)
+ *
+ *	Convert value s for termcap string capability named n into terminfo
+ *	format.
+ *
+ *	This code recognizes all the standard 4.4BSD %-escapes:
+ *
+ *	%%       output `%'
+ *	%d       output value as in printf %d
+ *	%2       output value as in printf %2d
+ *	%3       output value as in printf %3d
+ *	%.       output value as in printf %c
+ *	%+x      add x to value, then do %.
+ *	%>xy     if value > x then add y, no output
+ *	%r       reverse order of two parameters, no output
+ *	%i       increment by one, no output
+ *	%n       exclusive-or all parameters with 0140 (Datamedia 2500)
+ *	%B       BCD (16*(value/10)) + (value%10), no output
+ *	%D       Reverse coding (value - 2*(value%16)), no output (Delta Data).
+ *
+ *	Also, %02 and %03 are accepted as synonyms for %2 and %3.
+ *
+ *	Besides all the standard termcap escapes, this translator understands
+ *	the following extended escapes:
+ *
+ *	used by GNU Emacs termcap libraries
+ *		%a[+*-/=][cp]x	GNU arithmetic.
+ *		%m		xor the first two parameters by 0177
+ *		%b		backup to previous parameter
+ *		%f		skip this parameter
+ *
+ *	used by the University of Waterloo (MFCF) termcap libraries
+ *		%-x	 subtract parameter FROM char x and output it as a char
+ *		%ax	 add the character x to parameter
+ *
+ *	If #define WATERLOO is on, also enable these translations:
+ *
+ *		%sx	 subtract parameter FROM the character x
+ *
+ *	By default, this Waterloo translations are not compiled in, because
+ *	the Waterloo %s conflicts with the way terminfo uses %s in strings for
+ *	function programming.
+ *
+ *	Note the two definitions of %a: the GNU definition is translated if the
+ *	characters after the 'a' are valid for it, otherwise the UW definition
+ *	is translated.
