Control Files
The control files include files as the generic and package specific installation scripts (qinstall.shand
package_routines), the QPKG configuration file (qpkg.cfg),and the optional files with MD5 checksums and
configuration files. When the QPKG package is built these files are added to a gzip compressed tar archive,
which is added to a uncompressed tar archive as a workaround to limitations in the available busybox tools.
The header script extracts them to the installation directory.
