Unstall for Windows by PV-Soft, Petri Voutilainen

Once I tried one Uninstall for Windows program that didn't work in my
PC. So I decided to make my own.

UN4WIN.BAT menu requires 4DOS as your shell. Otherwise use TALLENNA.BAT
and VERTAILU.BAT direct (after changing them to match your system).

1. Saving settings with TALLENNA.BAT

   If TALLENNA.BAT is run under Windows, then Windows directory _should_
   be found in variable %windir. Otherwise you should change
   TALLENNA.BAT and VERTAILU.BAT

   Saves:   - WIN.INI
            - SYSTEM.INI
            - AUTOEXEC.BAT
            - CONFIG.SYS
            - file listings in both WINDOWS and WINDOWS\SYSTEM
              directories
            - tree structure in drives C: - F: (change TALLENNA.BAT and
              VERTAILU.BAT according to Your drives)

2. Comparing current and old settings

   Comparison is done with DOS's FC.EXE (FileCompare) and results are
   directed to EROT.TXT file. That file is then typed to screen with
   more option. You can replace that with your favourite editor.
