- * This adjtimex(1) is very similar in intent to adjtimex(8) by Steven
- * Dick <ssd@nevets.oau.org> and Jim Van Zandt <jrv@vanzandt.mv.com>
- * (see http://metalab.unc.edu/pub/Linux/system/admin/time/adjtimex*).
- * That version predates this one, and is _much_ bigger and more
- * featureful.  My independently written version was very similar to
- * Steven's from the start, because they both follow the kernel timex
- * structure.  I further tweaked this version to be equivalent to Steven's
- * where possible, but I don't like getopt_long, so the actual usage
- * syntax is incompatible.
- *
- * Amazingly enough, my Red Hat 5.2 sys/timex (and sub-includes)
- * don't actually give a prototype for adjtimex(2), so building
- * this code (with -Wall) gives a warning.  Later versions of
- * glibc fix this issue.
- *
- * This program is too simple for a Makefile, just build with:
- *  gcc -Wall -O adjtimex.c -o adjtimex

  * busyboxed 20 March 2001, Larry Doolittle <ldoolitt@recycle.lbl.gov>

- * on the BB_VER preprocessor macro.
