/*
  export-playerdb.c

  This program dumps db.global and db.players into an ASCII format into
  specified files.  Run this on the machine that you want to export a player
  database FROM.

  This should work on any type of architecture that can run the server; there
  are no architectural dependencies in here.  Drawbacks to this method:  it's
  slower, requires access to both machines (or cooperation from someone
  on the other machine), requires two steps, and generates large intermediate
  ASCII files.  If you know it's a 32 bit-32 bit conversion AND it requires
  and endian swap, use the other program that does it quicker and in one step.

  Benefits to this method:  Rob can use it.  ;) So can anyone with a 64-bit
  machine running a server (if such a thing exists).

  You must also use the import-playerdb.c program to import the database on
  the other end.

  Oh yeah; this falls under the Paradise copyright as stated in the server
  documentation; this is NOT under the GPL.

  Bug fixes:

  August 3, 1995    - Fixed bug that caused incorrect import for playernames
                      that contained spaces
