Version numbers are sprinkled all over the code (because of EVE$BUILD
requirements).

Most important is WPE_VERSION.DAT, a 1-line file which contains the overall
version number for WPE (and automatically for EDW).  This is the version
number which appears when the user types <Gold> Z.

Second in importance is WPE_MASTER.FILE, which contains the DOCUMENTATION for
revisions made to WPE.  This should be kept up to date, and synchronized with
the number in WPE_VERSION.DAT.

WPE.TPU and WPE_OPTIONS.TPU have separate version numbers, which appear in the
code in procedures wpe_module_ident and wpe_options_module_ident,
respectively.
