2 ** Path sandbox for the gentoo linux portage package system, initially
3 ** based on the ROCK Linux Wrapper for getting a list of created files
4 **
5 ** to integrate with bash, bash should have been built like this
6 **
7 ** ./configure --prefix=<prefix> --host=<host> --without-gnu-malloc
8 **
9 ** it's very important that the --enable-static-link option is NOT specified
