Directives are simple one line specifications with or without
arguments, e.g.,
Doit
Expires On
LoadModule my_mod modules/my_mod.so
Containers have a type and a name associated with them and they
in turn contain directives and/or containers, e.g.,
<MyContainer test1>
Expires Off
<DB devdb>
DBHost db.example.com
DBUser test_user
</DB>
</MyContainer>
Values may be quoted, e.g.
DBUser "test user"
But must be specified on a single line. To escape quotes
within a quoted string, use the '\' character.
