Cygwin and Rxvt

More of a reference to myself, this is the rxvt script I use:

@echo off
C:
chdir C:\cygwin\bin
set EDITOR=vi
set VISUAL=vi
set CYGWIN=codepage:oem tty binmode title
rxvt -sl 1500 -fn "Lucida Console-12" -bg black -fg white -sr -e bash --login -i

This is my keychain:

/usr/bin/keychain ~/.ssh/id_rsa
. ~/.keychain/${username}
