# Modification History:
#   July 7, 2008: Initial revision created to run the liftover utility on
#   the CGD (cgd.jax.org) imputed SNP data in comma-separated format
# 
# This is a ruby script for running liftover to map SNPs in a source
# comma-separated file to a destination file using a different NCBI genome

To get rid of shadows in screen captures:
defaults write com.apple.screencapture disable-shadow -bool true

To manipulate file attributes use xattr:
usage: xattr [-l] file [file ...]
       xattr -p [-l] attr_name file [file ...]
       xattr -w attr_name attr_value file [file ...]
       xattr -d attr_name file [file ...]

The first form lists the names of all xattrs on the given file(s).
