This is "dpkg". And it shows a bug: you don't test the return code of open(): bad, very bad.

Other bugs:

- flags packages which were removed by 'dpkg --remove', thus leaving configuration files:

dpkg - warning: ignoring request to remove midentd, only the config
 files of which are on the system.  Use --purge to remove them too.

- cannot handle some complicated dependencies, for instance introducing versions:

Removing libobgtk1 ...
dpkg: dependency problems prevent removal of gconv-modules:
 libgtk1.2 depends on gconv-modules | libc6 (<< 2.1); however:
  Package gconv-modules is to be removed.
  Version of libc6 on system is 2.1.2-10.
