+
+   $(basename $0) [-d <mail-domain>]
+
+\033[1mDescription\033[m
+
+  Script determins the 'last login' time (pop/imap) for each mailbox of a domain. 
+  If no domain was given at the command line, statistics is written for all mailboxes 
+  of all available domains.
+
+  Note:
+  this script expects a file '.las-log' at homedir of each mailbox. the timestamp of this
+  file is used as 'lost-login' time of the concerning mailbox.
+
+  Configure a dovecot service to touch '~/.last-login' at each pop/imap login. See also:
+     \033[1mhttps://wiki.dovecot.org/PostLoginScripting\033[m
+
+
+\033[1mOptions\033[m
+
+   -d 
+      The domain for which the 'last login' statistic is written. The default is to
+      write statistics for all available mail domains.
+
+\033[1mFiles\033[m

+\033[1mExample:\033[m
