+Usage: $0 [OPTION]... [VAR=VALUE]... [TARGET]
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+System types:
+  --target=TARGET               configure to run on target TARGET [detected]
+  --host=TARGET                 same as --target
+
+Installation directories:
+  --prefix=PREFIX               main installation prefix [/]
+
+Fine tuning of the installation directories:
+  --dynlibdir=DIR               shared library files [PREFIX/lib]
+  --libdir=DIR                  static library files [PREFIX/usr/lib/skalibs]
+  --includedir=DIR              include files for the C compiler [PREFIX/usr/include]
+  --datadir=DIR                 global configuration files [PREFIX/etc]
+  --sysdepdir=DIR               sysdeps directory [PREFIX/usr/lib/skalibs/sysdeps]
+
+Dependencies:
+  --with-sysdeps=DIR            use provided sysdeps in DIR [autodetected]
+  --with-include=DIR            add DIR to the list of searched directories for headers
+  --with-lib=DIR                add DIR to the list of searched directories for static libraries
+  --with-dynlib=DIR             add DIR to the list of searched directories for shared libraries
+
+Optional features:
+  --disable-shared              do not build shared libraries [enabled]
+  --disable-static              do not build static libraries [enabled]
+  --enable-slashpackage[=ROOT]  assume /package installation at ROOT [disabled]
+  --enable-cross=PREFIX         prefix toolchain executable names with PREFIX [none]
+
+skalibs options:
+  --enable-libc-replacements    use independent low-level primitives [disabled]
+  --enable-egd=PATH             support an EGD daemon listening on PATH as RNG [disabled]
+  --disable-ipv6                do not build IPv6 support [enabled]
+  --enable-iopause-select       prefer select() over poll() for iopause implementation [disabled]
+  --enable-tai-clock            assume the system clock is TAI-10 instead of UTC [disabled]
+  --enable-right-tz             assume the timezone is Olson's right/ instead of posix/ [disabled]
+  --enable-clock                use clock_gettime() instead of gettimeofday() [disabled]
+  --enable-monotonic            count time with CLOCK_MONOTONIC instead of CLOCK_REALTIME
+  --enable-force-devr           assume /dev/random exists and is valid [autodetection takes time]
+  --with-default-path=PATH      default executable search path [/usr/bin:/bin]
