Here is a script which automates the cpanp steps to update a custom source dir, which I find tedious and error prone. It assumes that there is a writeable directory (so it can do /cs --write /dir), which is also readable through URI file:///dir. Just Build your .tar.gz files, drop them in your custom source dir, and execute this script prior to running cpanp.

The script is a little unfinished in places (I didn't complete the part to read from ~/.xxx/config, and so $custom_src_dir is currently hardcoded).

One thing I think could be better is reload_indices takes a long time. If we could selectively reload the index on a single custom source, this would be very fast.

cpanp's scriptability is extremely well done. Great API.
