CONDITIONS FOR USE AND DISTRIBUTION:
-----------------------------------
PiCnix is being distributed under the user-distributed concept.
Please pass this package on to others and upload it to your favorite
computer bulletin board, but please make sure you give them the
complete PiCnix package, including this document. You also may not
misrepresent, either by commission or omission, the conditions
under which this program is being distributed.
If you use any of the utilities in this package on a regular
basis, it is requested that you register as a user of PiCnix by
sending a donation of $15 to the author. A registration form is
provided below for your convenience. Your donation will help
support improvements and additions to the PiCnix package. Your
registration will entitle you to receiving notices when updates are
available and will allow you to order the updated versions of the
package for only $10 per update. When you register, please include
your name and address so that notices of updates may be sent to you.
If you are registered as a user of the PiCnix package, the source
for all of these utilities, including the sources for the
underlying libraries, is available for an additional fee. The
source currently consists of over half a megabyte of 'C' source
code compatible with TURBO-C by Borland International. One library of
particular interest will be the code that provides for command line
argument expansion that is consistent with the argument expansion
provided by Unix. The only restrictions on the use of this source
code is that you may not create a competing product and a copyright
notice is required when using some of the included libraries. No
warranty is given that these sources will be suitable for any
particular purpose.
Of course, anyone may send in bug reports and suggestions for how
the package may be improved. Please try to describe the bug as
completely and accurately as possible along with a description of how
it may be reproduced consistently (if you know). I am very interested
in making the PiCnix package completely bug free, so please help me by
reporting any bugs you encounter. Suggestions for how the package may
be improved are always welcome, particularly suggestions about which
System V commands to implement next.
