+"Usage: $PROGNAME [options] [<build-type> ...]
+
+This script is used to ensure that all OpenSSL build variants compile
+properly. It can be used after modifying external/openssl/openssl.config
+and re-running import_openssl.sh to check that any changes didn't break
+the build.
+
+A <build-type> is a description of a given build of the library and its
+program. Its format is:
+
+ <compiler>-<system>-<arch>
+
+Where: <compiler> is either 'gcc' or 'clang'.
+ <system> is 'android', 'linux' or 'darwin'.
+ <arch> is 'arm', 'x86' or 'mips'.
+
+By default, it rebuilds the sources for the following build types:
+"
+ for BUILD_TYPE in $BUILD_TYPES; do
+ echo " $BUILD_TYPE"
+ done
+
+ echo \
+"However, you can pass custom values on the command-line instead.
+
+This scripts generates a custom Makefile in a temporary directory, then
+launches 'make' in it to build all binaries in parallel. In case of
+problem, you can use the --build-dir=<path> option to specify a custom
+build-directory, which will _not_ be removed when the script exits.
+
+For example, to better see why a build fails:
+
+ ./$PROGNAME --build-dir=/tmp/mydir
+ make -C /tmp/mydir V=1
+
+Valid options:
+
+ --help|-h|-? Print this message.
+ --build-dir=<path> Specify build directory.
+ --jobs=<count> Run <count> parallel build jobs [$NUM_JOBS].
+ -j<count> Same as --jobs=<count>.
+ --verbose Increase verbosity.
+ --quiet Decrease verbosity.
