dev_fetch_books - emulate svn:externals, sans annoying bits
The svn:externals functionality would be great if it could somehow not be consistently slow and noisy. This reinvention means you have to manually update it, but means you get to manually update it.
To install dtRdr, copy and paste the appropriate command in to your terminal.
cpanm
cpanm dtRdr
CPAN shell
perl -MCPAN -e shell install dtRdr
