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