Note

Indexer index new files on each launch
You can run it periodically at fixed times, dates, or intervals:
- Put the command in your crontab
- Use background service (DelayedJob, Sidekick, Resque) and instantiate the Repository class
Use of PStore as Key/Value storage (the closest filesystem structure)
You can easily create a new adapter (for example for Redis) extending the Cran::Adapter
Default logs in the log directory
Use semantic versioning (use semver CL to increase major/minor/patch)
It use parallel gem to parallelize the index process (speed up blocking operations like downloads)
Fully customizable log severity/adapters with Yell (you can change the severity updating the file cran.yaml)

Test

rake spec (from the project directory)

TODO

Check for process running writing a pid file
Move db file and logs in a system folder
