+Formatters are classes receiving packaging instructions and creating the
+appropriate package layout.
+
+There are three distinct formatters, each handling one of the different chrome
+formats:
+ - flat: essentially, copies files from the source with the same file system
+ layout. Manifests entries are grouped in a single manifest per directory,
+ as well as XPT interfaces.
+ - jar: chrome content is packaged in jar files.
+ - omni: chrome content, modules, non-binary components, and many other
+ elements are packaged in an omnijar file for each base directory.
+
+The base interface provides the following methods:
+ - add_base(path [, addon])
+ Register a base directory for an application or GRE, or an addon.
+ Base directories usually contain a root manifest (manifests not
+ included in any other manifest) named chrome.manifest.
+ The optional addon argument tells whether the base directory
+ is that of a packed addon (True), unpacked addon ('unpacked') or
+ otherwise (False).
+ - add(path, content)
+ Add the given content (BaseFile instance) at the given virtual path
+ - add_interfaces(path, content)
+ Add the given content (BaseFile instance) and link it to other
+ interfaces in the parent directory of the given virtual path.
+ - add_manifest(entry)
+ Add a ManifestEntry.
+ - contains(path)
+ Returns whether the given virtual path is known of the formatter.
+
+The virtual paths mentioned above are paths as they would be with a flat
+chrome.
+
+Formatters all take a FileCopier instance they will fill with the packaged
+data.
