* 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>
* It will autosense if it is built in a busybox environment, based
* on the BB_VER preprocessor macro.
