#input(pacman_pkg_path) ⇒ Object

Add a new source to this package. The exact behavior depends on the kind of package being managed.

For instance:

  • for FPM::Package::Dir, << expects a path to a directory or files.

  • for FPM::Package::RPM, << expects a path to an rpm.

The idea is that you can keep pumping in new things to a package for later conversion or output.

Implementations are expected to put files relevant to the ‘input’ in the staging_path
