Installing boolean
------------------

1. Log in as administrator
2. unzip boolean.zip c:\. It will extract a directory tree in c:\boolean
3. Now you have to set some system variable manually:
4. Right-click on 'My computer', select properties from the drop-down menu
5. Select the tab 'Advanced'
6. Click 'environment variables'
7. In the 'system variables' add a variable named 'GDSROOT',
   and add the path 'c:\boolean\6.2' (or the equivalent directory)
8. Edit the variable 'path' and add
   'c:\boolean\6.2\win32\bin'
9. The executable is also located in that path. Use the explorer to create a shortcut to the desktop or the start menu

If you cannot log in as administrator, you can set the GDSROOT variable as a user variable instead of
a system variable. However, you will not be able to change the path.


Notes.
- At startup you will always get an error message. Ignore it.
- Do not use the 'open' button on the toolbar. Instead, use the menu command to open GDSII or KEY files
- There is an error in the GDS save functionality. In the same directory is an executable with the name 'corrgds'
  You can use it to correct the error: 'corrgds inputfile outputfile'
  You can do this from the DOS prompt if your path is set correctly (see installation notes above)
