	The best way to do this is to make the group file on your computer and
copy it to the install disk.  Then write a little utility that copies the .grp
file to the directory that your program uses and that modifies the progman.ini
file to add the gropu to the list of groups.  That is:

[Groups]
Group1=C:\WINDOWS\ONE.GRP
Group2=C:\WINDOWS\TWO.GRP
Group3=C:\WINDOWS\THREE.GRP
Group..=C:\WINDOWS\(etc>).GRP
GroupN=C:\WINDOWS\N.GRP     <- This is the last current group
GroupN+1:\WINDOWS\N+1.GRP   <- This is your group

Notice: you will have to parse progman.ini to find the number of groups and
then add one to it to get the value your group should have.

If your initialization program has the option of several types of group
seteps, place each different setup in a different .grp file and at setup
time, copy over the appropriate .grp file.
