At first, we need to decide the file namefor the package ans the perl class name carries the file name. For example, a package Student should be in the file Student.pm. If it shouldbe called Bright::Student, it should be saved asBright/Student.pm, ie Student.pm in a directory named Bright. There is no formal relationship between directory name and modules. That is just grouping for convenience.

Since Django doesn't like to handle static files on production systems, we always have to configure a web server like nginx or apache webserver to serve static files. On the other hand, its easy to host static files to Amazon S3. The S3 configuration for static files is easy, but saving user uploaded files for Django web app may raise some permission issues. Here is how we have configured the Django-S3-Mezzanine blog.
