/* NOTES:
-
 
34
 * 1 - Various functions were adapted from FreeBSD (copyright holders noted above)
-
 
35
 *     these functions are identified with comments.
-
 
36
 *
-
 
37
 * 2 - Some of these have since appeared in libc. They remain here for various
-
 
38
 *     reasons, such as the eventual integration of garbage collection for things
-
 
39
 *     that allocate memory and don't automatically free it.
-
 
40
 *
-
 
41
 * 3 - Things that expect a pointer to an allocated string do _no_ sanity checking
-
 
42
 *     if developing on a simulator with no debugger, take care :)
