Log Message:
-----------
wrap a slew of boilerplate infrastructure similar to the benchmark suite so
that we have nice argument process, verbose/quiet options, help & instructions,
and clean formatted output. some basic adjustments made to use printf instead
of echo

+
+This script is used to test BRL-CAD's explicit surface polygonal
+conversion capabilities. It takes a list of one or more geometry
+files and for every geometry object in the file, it facetizes the
+object into NMG and BoT format. The script times, tabulates, and
+reports conversion results.
+
+The script is useful for a variety of purposes including for
+developers to perform regression testing as BRL-CAD's conversion
+capabilities are modified and improved. It's also useful for users to
+get a report of which objects in a given BRL-CAD geometry database
+will convert, what percentage, and how long the conversion will take.
+
+There are several environment variables that will modify how this
+script behaves:
+
+ MAXTIME - maximum number of seconds allowed for each conversion
+ VERBOSE - turn on extra debug output for testing/development
+ QUIET - turn off all printing output (writes results to log file)
+ INSTRUCTIONS - display these more detailed instructions
+
+The MAXTIME option specifies how many seconds are allowed to elapse
+before the conversion is aborted. Some conversions can take days or
+months (or infinite in the case of a bug), so this places an upper
+bound on the per-object conversion time.
