 # The configuration reader will do what it can to translate everything into
 # new style config hash tables, including merging $target and debug-$target
 # if they are similar enough.
+#
+# The configuration hashes can refer to templates in two different manners:
+#
+# - as part of the hash, one can have a key called 'inherit_from' that
+#   indicate what other configuration hashes to inherit data from.
+#   These are resolved recursively.
+#
+#   Inheritance works as a set of default values that can be overriden
+#   by corresponding attribute values in the inheriting configuration.
+#
+#   If several configurations are given in the 'inherit_from' array, the
+#   values of same attribute are concatenated with space separation.
+#   With this, it's possible to have several smaller templates for
+#   different configuration aspects that can be combined into a complete
+#   configuration.
+#
+#   Example:
+#
+#      "foo" => {
+#              template => 1,
+#              haha => "haha",
+#              hoho => "ho"

+#      "laughter" => {
+#              inherit_from => [ "foo", "bar" ],
+#      }
+#
+#      The entry for "foo" will become as follows after processing:
+#
+#      "laughter" => {
+#              haha => "haha",
+#              hoho => "ho ho",
+#              hehe => "hehe"
+#      }
+#
+#   Note 1: any entry from the table can be used as a template.
+#   Note 2: pure templates have the attribute 'template => 1' and cannot
+#           be used as targets.
+#
+# - instead of a string, one can have a code block of the form
+#   'sub { /* your code here */ }', where the arguments are the list of
+#   inherited values for that key.  In fact, the concatenation of strings
+#   is really done by using 'sub { join(" ",@_) }' on the list of inherited
+#   values.
