To create a new angel, use angel 'newangel' in 'developers' (angel developers/newangel). It will create an empty angel.
After modifying and saving the angel, copy the angel into the directory you want (within the angel base directory) and run:
$angel –-create-index $PWD
This will update the index file for the current directory.
To change the order of angels within a directory, change the index file and move the entries into the right order.
To offer angels for download on a website, create a tar.gz archive of the angel (single angel or directory) and host it on your website.
