# USAGE
# will never source source .files or .directories
# all option arguments that contain globs/wildcards must be quoted to avoid expansion
# p option excludes additional paths below of the given name (and depth)
# d option sets the directory depth which is current directy by default, 0 is all
# x excludes file globs
# f inclucdes only file globs otherwise it's all except .files
# if no directory is given it will attempt to source the present working directory
# example:
# source_dir -p "archive" -x '"*.off" "*.md"' -d 0 # $DIR/$SUBDIR
