Ah, the things you find while cleaning up a bit...

This appears to be a conio object for jsexec... I don't remember writing this
and it has a couple scary looking warnings when compiling:

js_conio.c: In function 'js_conio_puttext':
js_conio.c:666: warning: passing argument 2 of 'JS_GetArrayLength' makes pointer from integer without a cast
js_conio.c:680: warning: passing argument 2 of 'JS_GetElement' makes pointer from integer without a cast

Adding to CVS so I can player with it as much as I want.  :-)
