I like the idea of working in the `/tmp` directory - prevents creating a lot of crap in case of failures, but rather than `$HOME` we ought to move to current directory:

     mv $TMPDIR ./$PRJ_NAME

So it gets created in current dir. (I use my `~/Documents/workspace` for svn projects, `~/Documents/git` for git and so on, so planning on issuing this command in a directory where I want my files to be created, rather than move it around from home dir to somewhere else...)
