# This is a companion tool to vee that is used internally by vee; if
# you wish to write your own custom scripts to manage your posts, then
# then I suggest using this tool for extracting out the relevant bits
# you wish to use for your scripts (e.g., title (-t), date (-d), etc).

# Usage:
#   echo "path/to/*.raw" | veecat [-t | -d | -a ]  # I know this is funky

# preserve new lines
