-1.1 Dispatch table
-──────────────────
-
-  `%dispatch' has the pre-defined list. Learn the list directly from
-  `leo.pl', it's self-explanatory. Or check the sub `HelpMessage', it
-  explains what each command does.
-
-  For example, `documents' will archive `$ENV{HOME}/documents' to
-  `/tmp/archive/documents_$ymd.tar' where `$ymd' is current date in
-  `YYYY-MM-DD' format.

-  │                 "-C", "$ENV{HOME}/documents",
-  │                 "andinus.org.gpg", "archive.org.gpg");

-  Currently I generate the dispatch table with a function & only special
-  profiles are added manually like above. `journal' is a special profile
-  because I don't want encryption on it.

+  Profile is a simple hash table which contains the list of profiles.
+  The profiles are mapped to a list of file paths relative to `$HOME'
+  which are to be archived.
 
-  I alias paths like `.ssh' to make it convenient to type:
+  Complex profiles are hard coded & simple ones are generated. Complex
+  profiles include profiles that have multiple files or are a mix or
+  files & directories. Simple profiles are profiles with just single
+  directory.
 
-  ┌────
-  │ # Aliases for inconvenient paths.
-  │ $dispatch{ssh} = $dispatch{".ssh"};
-  │ $dispatch{pass} = $dispatch{".password-store"};
-  └────
+  You can run `help' to see all the profiles along with the paths.
