# This is a companion tool to vee that is used internally by vee; if
# you plan on writing custom scripts to manage your posts, I do suggest
# using `veels` as the primary was of listing the files for iteration
# or for whatever you use it for.

#Usage:
#  veels [ -d dir/with/.raw/files ] [ -r ] [ -e raw|txt ]
