Satis Repository Builder
Take your composer.lock file and build a Satis repository up in S3 easily!
curl -sS https://getcomposer.org/installer | php ./composer.phar install php composer.phar create-project composer/satis --stability=dev --keep-vcs satis
bin/build.php to set your S3 information.
Yes, that needs to be changed. I've been waiting 4 months for me to fix it. Not looking likely! :D
Now you just run
./bin/build.php /path/to/your/composer.lock and it does the rest!
There's some S3 permissions issues that will come up, which someone much smarter than I about AWS can probably give about 2 seconds of input and fix.
