version 0.1
 this release was based on a specific sk binary; MAGIC1 / MAGIC2
 values were extracted. Program tests whether the syscall is
 modified, reports the active sk version and attempts to disable
 the sk binary.

version 0.2
 extra MAGIC1/MAGIC2 values were added after a new sk binary was
 found.

version 0.3
 more MAGIC1/MAGIC2 values added.

version 0.4
 code rewrite; used partial sk-1.3b code to find out where the
 rootkit tries to install itself. The syscall code is examined to
 find the MAGIC1/MAGIC2 values.

version 0.4a
 added license, readme and changelog files.

version 0.4b
 - more strict checking; there were some false positive reports.
 - copied 2 defines from the linux kernel into syscall.h; this
   might solve some compile problems.
 - display message if rootkit wasn't found.
 - display message if skdetect is run as non-root user.
 - updated Makefile, included header-files.
