2 # A v. 2.0 Debian package is nothing but an ar(1) archive that contains
3 # three members:
4 # 1. A debian-binary file containing the string "2.0" and a newline,
5 # 2. A compressed tar archive with a name of control,
6 # 3. A compressed tar archive with a name of data.
7 # (See https://en.wikipedia.org/wiki/Deb_%28file_format%29.) Make one.

9 # There are other ways to do this, but they tend to be so complex and
10 # badly-documented that I found it easier to just roll my own.
