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