# The following command works for downloading when using Git for Windows:
# curl -LOf http://gist.githubusercontent.com/kmorcinek/2710267/raw/.gitignore
#
# Download this file using PowerShell v3 under Windows with the following comand:
# Invoke-WebRequest https://gist.githubusercontent.com/kmorcinek/2710267/raw/ -OutFile .gitignore
#
# or wget:
# wget --no-check-certificate http://gist.githubusercontent.com/kmorcinek/2710267/raw/.gitignore
