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