+ * 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.
