# Hi there!  Welcome to the yt installation script.
#
# This script is designed to create a fully isolated Python installation
# with the dependencies you need to run yt.
#
# There are a few options, but you only need to set *one* of them.  And
# that's the next one, DEST_DIR.  But, if you want to use an existing HDF5
# installation you can set HDF5_DIR, or if you want to use some other
# subversion checkout of yt, you can set YT_DIR, too.  (It'll already
# check the current directory and one up.
#
# If you experience problems, please visit the Help section at 
# http://yt-project.org.
