26 * Known difference between busybox dpkg and the official dpkg that i dont
27 * consider important, its worth keeping a note of differences anyway, just to
28 * make it easier to maintain.
29 * - The first value for the Confflile: field isnt placed on a new line.
30 * - The <package>.control file is extracted and kept in the info dir.
31 * - When installing a package the Status: field is placed at the end of the
32 * section, rather than just after the Package: field.
33 * - Packages with previously unknown status are inserted at the begining of
36 * Bugs that need to be fixed
37 * - (unknown, please let me know when you find any)
