11     # Applicability.
12     #
13     # This script is intended for the common case on Red Hat systems
14     # where mail users have mail folders in their home directories
15     # under /home, and have inboxes in /var/spool/mail/
16     #==================================================================
17     # Change the value of the elements in this section as required.
18    
19     #This is a list of folders, one per line. This does not
20     #include the inboxes. This might be prepared starting with
21     #the output of "find /home -type d".
22     FOLDERLIST=/root/migrate/folderlist
23     # folder is the existing mbox folder being migrated.
24     # It is a path under /home.
25     # eg if oldfolder is fred/personal, then folder is personal,
26     # user is fred.
27    
28     #Specify the location of the new location for mail folders.
29     #This cannot be the same as the old location because it will
30     #create directory names that contend with existing file names.
