82 /* XXX: DPKG_INCOMPATIBILITY: deb_extract will extract all of the
83 data file names with a '.' as the first character. I've taught
84 opkg how to cope with the presence or absence of the '.', but
85 this may trip up dpkg.
87 For all I know, this could actually be a bug in opkg-build. So,
88 I'll have to try installing some .debs and comparing the *.list
91 If we wanted to, we could workaround the deb_extract behavior
92 right here, by writing to a tmpfile, then munging things as we
93 wrote to the actual stream. */
