6 | Debian Archive File (.deb) | |
7 | ||
8 | This Class handles all the operations performed directly on .deb | |
9 | files. It makes use of the AR and TAR classes to give the necessary | |
10 | external interface. | |
11 | ||
12 | There are only two things that can be done with a raw package, | |
13 | extract it's control information and extract the contents itself. | |
14 | ||
15 | This should probably subclass an as-yet unwritten super class to | |
16 | produce a generic archive mechanism. | |
17 | ||
18 | The memory control file extractor is useful to extract a single file | |
19 | into memory from the control.tar.gz | |
