gpm will install different types of packages. Each Package defines its type, plugin based handlers install packages of different types.
Packages can easily be defined with a npm package.json-like package.json file, and–if necessary–an accompanying <type>.json file with extra information for the handler.
\ cannot be used in repository names or package names, it is used as the delimiter between repository and package (e.g. quaddicted/quoth).
If package.json does not have a files section, a file of <packagename>.zip is assumed by most handlers.
Custom fields in ~package.json~.
