Options:
--admindir= Use instead of /var/lib/dpkg
--root= Install on alternative system rooted elsewhere
--instdir= Change inst&#39;n root without changing admin dir

Comparison operators for --compare-versions are:
lt le eq ne ge gt (treat empty version as earlier than any version);
lt-nl le-nl ge-nl gt-nl (treat empty version as later than any version);
< << <= = >= >> > (only for compatibility with control file syntax).
Use `dselect&#39; or `aptitude&#39; for user-friendly package management.
