+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 [/]
+  --exec-prefix=EPREFIX         installation prefix for executable files [PREFIX]
+
+Fine tuning of the installation directories:
+  --dynlibdir=DIR               shared library files [PREFIX/lib]
+  --bindir=DIR                  user executables [EPREFIX/bin]
+  --sbindir=DIR                 admin executables [EPREFIX/sbin]
+  --libexecdir=DIR              package-scoped executables [EPREFIX/libexec]
+  --libdir=DIR                  static library files [PREFIX/lib]
+  --includedir=DIR              include files for the C compiler [PREFIX/include]
+
+Dependencies:
+  --with-sysdeps=DIR            use sysdeps in DIR [/usr/lib/skalibs/sysdeps]
+  --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:
+  --enable-shared               build shared libraries [disabled]
+  --disable-static              do not build static libraries [enabled]
+  --disable-allstatic           do not prefer linking against static libraries [enabled]
+  --enable-static-libc          make entirely static binaries [disabled]
+  --enable-slashpackage[=ROOT]  assume /package installation at ROOT [disabled]
+  --enable-cross=PREFIX         prefix toolchain executable names with PREFIX [none]
