74 data file names with a '.' as the first character. I've taught
75 opkg how to cope with the presence or absence of the '.', but
76 this may trip up dpkg.
77
78 For all I know, this could actually be a bug in opkg-build. So,
79 I'll have to try installing some .debs and comparing the *.list
80 files.
81
82 If we wanted to, we could workaround the deb_extract behavior
83 right here, by writing to a tmpfile, then munging things as we
84 wrote to the actual stream. */
