#GROUP painters picasso mondrian klee
#EXCLUDE ZWCAD_PRO GROUP painters
#EXCLUDE ZWCAD_PRO USER bob
#EXCLUDE ZWCAD_PRO INTERNET 123.123.123.* 
#This options file:
#Prevents the users picasso, mondrian, and klee from using the feature ZWCAD_PRO on any system on the network.
#Prevents the user bob from using the feature ZWCAD_PRO on any system on the network.
#Prevents any user logged into a host with an IP address in the range 123.123.123.0 through 123.123.123.255 from using the feature ZWCAD_PRO.
#Allows any other user, as long as they are not on the excluded IP addresses, and they are not a member of the painters GROUP, and they are not bob, to use feature ZWCAD_PRO (by implication).
#Note that bob could have been added to the group painters. However, painters might be used for some other purpose in the future so the license administrator chose to handle bob as a special case here.In this case, the two EXCLUDE statements concatenate to create a list of four users.
