my git configuration file
my vim configuration files
my X11 and OS X keyboard layouts

my daily calculator.

can also execute arbitrary ruby expressions.
installs to $HOME/custom

simple tab-completion for common folders

type quickcd to fav' the current folder, say /usr/bin/myfolder.
an executable named myfolder gets added to ~/quickfolders.
if that folder is in your path, typing "cd `my<TAB>`" should expand
to "cd `myfolder`", which itself expands to "cd /usr/bin/myfolder".
a version of seq which pads with zeroes

with the regular seq:
  > seq 04
  1
  2
  3
  4

with this variant:
  > seq 04
  01
  02
  03
  04
the numeric sum of all input lines.

I'm sure awk can do this in one line, but I don't know awk.
