** LIBRARY: <string.h>
** SYNOPSIS: concatenate strings (s2 into s1)
**
** DESCRIPTION:
** 		The strcat() and strncat() functions append a copy of the null-
**	terminated string s2 to the end of the null-terminated string s1, then
**	add a terminating `\0'.  The string s1 must have sufficient space to hold
**	the result.
