makewzd.c

/*
 *   Binary to WZD conversion utility
 *   this tool comes from the OZ-7xx Developement Kit
 *   by Alexander R. Pruss 
 *
 *      If (and only if) you use any of the read*() or write*()
 *      functions and publically release your program, you MUST apply to
 *      Alexander R. Pruss (ap85@georgetown.edu) for an owner ID for
 *      your program and you MUST link an owner ID into your program
 *      with makewzd or equivalent.  For in-house testing, you may use
 *      the ID of 65535, but not for public release.  Owner IDs will be
 *      granted free of charge.  Specify what programs you plan to write
 *      and how many IDs you'd like (you can get up to ten each time you
 *      apply). It is illegal to use either an owner ID not assigned to
 *      you or the ID of 65535 for publically released programs.  A
 *      program counts as publically released if it is posted in a
 *      publically available way (e.g., a web site) or sold to the
 *      public.
 *      There is, however, one exception to this rule.  If you write a
 *      program that processes files generated by other applications
 *      which duly have owner IDs assigned, e.g., a program that reads
 *      font files, or a file manager, or a multi-purpose binary file
 *      viewer, you do not need to apply for an owner ID.
