Provides information about a binary package archive.
If no control-file-names are specified then it will print a summary of the contents of the package as
well as its control file.
If any control-file-names are specified then dpkg-deb will print them in the order they were specified;
if any of the components weren't present it will print an error message to stderr about each one and
exit with status 2.
