   2 // Name:        splitwise.cpp
   3 // Purpose:     Use this to split wxwin2.wse in the distrib/msw directory
   4 //              into wisetop.txt, wisebott.txt. This allows you to do the
   5 //              following:
   6 //
   7 //              1) Edit the existing wxwin2.wse in WISE Install.
   8 //              2) Call splitwise.exe to split off the non-file bits (i.e.
   9 //                 preserve everything except the "item: Install File" lines).
  10 //              3) Call makewise.bat to generate a new wxwin2.wse from
  11 //                 wisetop.txt, wisebott.txt and the file list generated
  12 //                 from the files in deliver\wx (which themselves have been
  13 //                 put there by zipdist.bat).
  14 //
  15 //              If you don't wish to change the WISE settings, then there's no
  16 //              need to use splitwise, but it's very likely that settings will
  17 //              be altered, e.g. to change the version number, what's installed,
  18 //              etc.
