+NAME
+	xrealloc () - get more memory or bust
+INDEX
+	xrealloc () uses realloc ()
+SYNOPSIS
+	char   *my_memory;
+
+	my_memory = xrealloc (my_memory, 42);
+	/ * my_memory gets (perhaps new) address of 42 chars * /
+
+DESCRIPTION
+
+	Use xrealloc () as an "error-free" realloc ().It does almost the same
+	job.  When it cannot honour your request for memory it BOMBS your
+	program with a "virtual memory exceeded" message.  Realloc() returns
+	NULL and does not bomb your program.
