31 #               just as well use "make INSTALL_PREFIX=/whatever install".

33 # --test-sanity Make a number of sanity checks on the data in this file.
34 #               This is a debugging tool for OpenSSL developers.

36 # --cross-compile-prefix Add specified prefix to binutils components.

223 # The configuration reader will do what it can to translate everything into
224 # new style config hash tables, including merging $target and debug-$target
225 # if they are similar enough.
226 #
227 # The configuration hashes can refer to templates in two different manners:
228 #
229 # - as part of the hash, one can have a key called 'inherit_from' that
230 #   indicate what other configuration hashes to inherit data from.
231 #   These are resolved recursively.
232 #
233 #   Inheritance works as a set of default values that can be overriden
234 #   by corresponding attribute values in the inheriting configuration.
235 #
236 #   If several configurations are given in the 'inherit_from' array, the
237 #   values of same attribute are concatenated with space separation.
238 #   With this, it's possible to have several smaller templates for
239 #   different configuration aspects that can be combined into a complete
240 #   configuration.
241 #
242 #   Example:
243 #
244 #       "foo" => {
245 #               template => 1,
246 #               haha => "haha",
247 #               hoho => "ho"
248 #       },
249 #       "bar" => {
250 #               template => 1,
251 #               hoho => "ho",
252 #               hehe => "hehe"
253 #       },
254 #       "laughter" => {
255 #               inherit_from => [ "foo", "bar" ],
256 #       }
257 #
258 #       The entry for "foo" will become as follows after processing:
259 #
260 #       "laughter" => {
261 #               haha => "haha",
262 #               hoho => "ho ho",
263 #               hehe => "hehe"
264 #       }
265 #
266 #   Note 1: any entry from the table can be used as a template.
267 #   Note 2: pure templates have the attribute 'template => 1' and cannot
268 #           be used as targets.
269 #
270 # - instead of a string, one can have a code block of the form
271 #   'sub { /* your code here */ }', where the arguments are the list of
272 #   inherited values for that key.  In fact, the concatenation of strings
273 #   is really done by using 'sub { join(" ",@_) }' on the list of inherited
274 #   values.
275 #
276 #   Example:
277 #
278 #       "foo" => {
279 #               template => 1,
280 #               haha => "ha ha",

285 #               template => 1,
286 #               haha => "ah",
287 #               hoho => "haho",
