247 # The configuration reader will do what it can to translate everything into
248 # new style config hash tables, including merging $target and debug-$target
249 # if they are similar enough.
250 #
251 # The configuration hashes can refer to templates in two different manners:
252 #
253 # - as part of the hash, one can have a key called 'inherit_from' that
254 #   indicate what other configuration hashes to inherit data from.
255 #   These are resolved recursively.
256 #
257 #   Inheritance works as a set of default values that can be overriden
258 #   by corresponding attribute values in the inheriting configuration.
259 #
260 #   If several configurations are given in the 'inherit_from' array, the
261 #   values of same attribute are concatenated with space separation.
262 #   With this, it's possible to have several smaller templates for
263 #   different configuration aspects that can be combined into a complete
264 #   configuration.
265 #
266 #   Example:
267 #
268 #       "foo" => {
269 #               template => 1,
270 #               haha => "haha",
271 #               hoho => "ho"
272 #       },
273 #       "bar" => {
274 #               template => 1,
275 #               hoho => "ho",
276 #               hehe => "hehe"
277 #       },
278 #       "laughter" => {
279 #               inherit_from => [ "foo", "bar" ],
280 #       }
281 #
282 #       The entry for "foo" will become as follows after processing:
283 #
284 #       "laughter" => {
285 #               haha => "haha",
286 #               hoho => "ho ho",
287 #               hehe => "hehe"
288 #       }
289 #
290 #   Note 1: any entry from the table can be used as a template.
291 #   Note 2: pure templates have the attribute 'template => 1' and cannot
292 #           be used as targets.
293 #
294 # - instead of a string, one can have a code block of the form
295 #   'sub { /* your code here */ }', where the arguments are the list of
296 #   inherited values for that key.  In fact, the concatenation of strings
297 #   is really done by using 'sub { join(" ",@_) }' on the list of inherited
298 #   values.
299 #
300 #   Example:
301 #
302 #       "foo" => {
303 #               template => 1,
304 #               haha => "ha ha",
