Demeter is a configurable data-harvesting application.
demeter get
Demeter allows the user to specify common data-downloading operations through configuration and convention as much as possible, while still allowing the user to drop down to code to accomplish actions that cannot be represented in configuration.
Demeter requires a configuration file to be really useful. You can see
some examples of them in the config directory. These should be YAML
documents.
Adding a new downloader is as straightforward as adding a new perl module in
the App::Demeter::Source namespace. Because downloaders are perl modules
that means they can be versioned, installed, have dependencies, and all
the other good things about having perl modules.
You do not need to install this application to use it. If you do want to install it, you can do so with the following commands.
perl Build.PL
./Build
./Build test
./Build install
The documentation is a bit non-existent, and could do with some improvement. You can try your luck with perldoc.
perldoc App::Demeter
