64 bit vs 32 bit

* links in your ubuntu root directories for 64 bit stuff

Your root directory has some important directories in it. For example,

$ cd /
$ ls
bin    dev   lib32   tmp
boot   etc   lib64   usr
cdrom  home  lib

If you're confused about whether you should be using or linking your flooxs libraries to lib, lib32, or lib64, just use "lib," since what's in there is linked to whatever is the default (in my case, lib files are really just links to lib64 files).
