Subject: Query on usages of 'public-domain' software

You may give away any of the public-domain programs without contacting
the authors.  It doesn't matter that these programs will be used for
commercial applications UNLESS the program documentation specifically
prohibits commercial use.  Even then, unless it's copyrighted that
doesn't mean anything.  Public-Domain is Public-Domain - for ALL to
use in any manner they deem fit.

Public-Domain programs should not be sold for profit, but a
"reasonable" charge can be made for copying and/or customization as
required.  The definition of "reasonable" is vague, but I'd say you
should let your conscience be your guide.  Charge only a small fee for
copying and make your money on a per-hour labor charge for
customization.  Typical free-lance computer consultant fees are $25 to
$50 per hour or "by the piece" if it will take too many hours to make
using the "per-hour" charge practical.  What you charge for an hourly
fee will be decided by what the traffic will bear and by what value
you place on your time.  Don't under-sell yourself and don't forget
your overhead costs, such as disks, computer time, travel, phone
calls, overtime, etc.
