31 #               just as well use "make INSTALL_PREFIX=/whatever install".
32 #
33 # --test-sanity Make a number of sanity checks on the data in this file.
34 #               This is a debugging tool for OpenSSL developers.
35 #
36 # --cross-compile-prefix Add specified prefix to binutils components.

63 # DES_RISC1     use different DES_ENCRYPT macro that helps reduce register
64 #               dependancies but needs to more registers, good for RISC CPU's

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

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