bin: a new binginning
I used to use 'bin' for my setup scripts, so its history will
undoubtably be confusing. However, I've recently (through reading The
UNIX Programming Environment) become a fan of putting individual scripts
in ~/bin, so I now wish to version control it.
To start out, we have 'csum', a basic column-sum via awk .
