0mp c45c4bfe6a Tell the world how to convert gigabytes to bytes with units(1) easily
It turns out that units(1) is not as horrible to use in scripts
as I initially thought. When the --terse flag is combined
with an appropriate output format (set via --output-format),
units(1) is actually capable of producing very nice results.
For example:

    units -o %0.f -t '4 gigabytes' bytes

is is just going to print out the expected value of 4294967296.

There is no time to waste. People have to know about it.

I am adding an example for this at the top of the examples section
because this is what users are most likely looking for.

# $FreeBSD$

This is a program which I wrote as a clone of the UNIX 'units'
command.  I threw it together in a couple days, but it seems to work,
with some restrictions.  I have tested it under DOS with Borland C and
Ultrix 4.2, and SunOS 4.1.  

This program differs from the unix units program in the following
ways:
   it can gracefully handle exponents larger than 9 in output
   it uses 'e' to denote exponentiation in numbers
   prefixes are listed in the units file
   it tries both -s and -es plurals
   it allows use of * for multiply and ^ for exponentiation in the input
   the output format is somewhat different
