+Build info files
+================
+
+The build.info files that are spread over the source tree contain the
+minimum information needed to build and distribute OpenSSL.  It uses a
+simple and yet fairly powerful language to determine what needs to be
+built, from what sources, and other relationships between files.
+
+For every build.info file, all file references are relative to the
+directory of the build.info file for source files, and the
+corresponding build directory for built files if the build tree
+differs from the source tree.
+
+When processed, every line is processed with the perl module
+Text::Template, using the delimiters "{-" and "-}".  The hashes
+%config and %target are passed to the perl fragments, along with
+$sourcedir and $builddir, which are the locations of the source
+directory for the current build.info file and the corresponding build
+directory, all relative to the top of the build tree.
+
+To begin with, things to be built are declared by setting specific
+variables:
+
+    PROGRAMS=foo bar
+    LIBS=libsomething
+    ENGINES=libeng
+    SCRIPTS=myhack
+    EXTRA=file1 file2
+
+Note that the files mentioned for PROGRAMS, LIBS and ENGINES *must* be
+without extensions.  The build file templates will figure them out.
+
+For each thing to be built, it is then possible to say what sources
+they are built from:
+
+    PROGRAMS=foo bar
+    SOURCE[foo]=foo.c common.c
+    SOURCE[bar]=bar.c extra.c common.c
+
+It's also possible to tell some other dependencies:
+
+    DEPEND[foo]=libsomething
+    DEPEND[libbar]=libsomethingelse
+
+(it could be argued that 'libsomething' and 'libsomethingelse' are
+source as well.  However, the files given through SOURCE are expected
+to be located in the source tree while files given through DEPEND are
+expected to be located in the build tree)
+
+For some libraries, we maintain files with public symbols and their
+slot in a transfer vector (important on some platforms).  It can be
+declared like this:
+
+    ORDINALS[libcrypto]=crypto
+
+The value is not the name of the file in question, but rather the
+argument to util/mkdef.pl that indicates which file to use.
+
+One some platforms, shared libraries come with a name that's different
+from their static counterpart.  That's declared as follows:
+
+    SHARED_NAME[libfoo]=cygfoo-{- $config{shlibver} -}
+
+The example is from Cygwin, which has a required naming convention.
+
+Sometimes, it makes sense to rename an output file, for example a
+library:
+
+    RENAME[libfoo]=libbar
+
+That lines has "libfoo" get renamed to "libbar".  While it makes no
+sense at all to just have a rename like that (why not just use
+"libbar" everywhere?), it does make sense when it can be used
+conditionally.  See a little further below for an example.
+
+For any file to be built, it's also possible to tell what extra
+include paths the build of their source files should use:
+
+    INCLUDE[foo]=include
+
+It's possible to have raw build file lines, between BEGINRAW and
+ENDRAW lines as follows:
+
+    BEGINRAW[Makefile(unix)]
+    haha.h: {- $builddir -}/Makefile
+        echo "/* haha */" > haha.h
+    ENDRAW[Makefile(unix)]
+
+The word withing square brackets is the build_file configuration item
+or the build_file configuration item followed by the second word in the
+build_scheme configuration item for the configured target within
+parenthesis as shown above.  For example, with the following relevant
+configuration items:
+
+   build_file   => "build.ninja"
+   build_scheme => [ "unified", "unix" ]
+
+... these lines will be considered:
+
+   BEGINRAW[build.ninja]
+   build haha.h: echo "/* haha */" > haha.h
+   ENDRAW[build.ninja]
+
+   BEGINRAW[build.ninja(unix)]
+   build hoho.h: echo "/* hoho */" > hoho.h
+   ENDRAW[build.ninja(unix)]
+
+See the documentation further up for more information on configuration
+items.
+
+Finally, you can have some simple conditional use of the build.info
+information, looking like this:
+
+    IF[1]
+     something
+    ELSIF[2]
+     something other
+    ELSE
+     something else
+    ENDIF
+
+The expression in square brackets is interpreted as a string in perl,
+and will be seen as true if perl thinks it is, otherwise false.  For
+example, the above would have "something" used, since 1 is true.
+
+Together with the use of Text::Template, this can be used as
+conditions based on something in the passed variables, for example:
+
+    IF[{- $config{no_shared} -}]
+      LIBS=libcrypto
+      SOURCE[libcrypto]=...
+    ELSE
+      LIBS=libfoo
+      SOURCE[libfoo]=...
+    ENDIF
+
+or:
+
+    # VMS has a cultural standard where all libraries are prefixed.
+    # For OpenSSL, the choice is 'ossl_'
+    IF[{- $config{target} =~ /^vms/ -}]
+     RENAME[libcrypto]=ossl_libcrypto
+     RENAME[libssl]=ossl_libssl
+    ENDIF
