Found the truncate command which is much easier than DD and also
creates a sparse file or resizes a sparse file larger or smaller.

Common loopback device commands. Useful for dealing with filesystems
in a file.

Creating sparse files for loopback images can be done with the dd
command. The ascii_only strips all non-ascii characters out of a
string.

Things like vimrc that I use everywhere, my current .bash_aliases,
a complicated imapfilter config from PureStorage, and a BASH script
that writes out to a log file and the stdout/stderr at the same time.

Adding an additional information line to the README file.
