+Usage: $0 [OPTION]... [TARGET]
+
+Defaults for the options are specified in brackets.
+
+System types:
+  --target=TARGET               configure to run on target TARGET [detected]
+  --host=TARGET                 same as --target
+
+Installation directories:
+  --prefix=PREFIX               main installation prefix [/]
+  --exec-prefix=EPREFIX         installation prefix for executable files [PREFIX]
+
+Fine tuning of the installation directories:
+  --dynlibdir=DIR               shared library files [PREFIX/lib]
+  --bindir=BINDIR               user executables [EPREFIX/bin]
+  --libexecdir=DIR              package-scoped executables [EPREFIX/libexec]
+  --libdir=DIR                  static library files [PREFIX/lib]
+  --includedir=DIR              C header files [PREFIX/include]
+  --sysconfdir=DIR              global configuration files [PREFIX/etc]
+  --pkgconfdir=DIR              pkg-config .pc files [PREFIX/lib/pkgconfig]
+${configure_help_install}
+ If no --prefix option is given, by default libdir (but not dynlibdir) will be
+ /usr/lib, and includedir will be /usr/include.
+
+Dependencies:
+  --with-sysdeps=DIR            use sysdeps in DIR [PREFIX/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
+  --with-pkgconfig[=PROG]       use pkg-config to look for dependencies
+${configure_help_dependencies}
+ If no --prefix option is given, by default sysdeps will be fetched from
+ /usr/lib/skalibs/sysdeps.
+
+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]
+  --disable-all-pic             do not build executables or static libs as PIC [enabled]
+  --enable-pkgconfig            Build and install .pc files for pkg-config [disabled]
+  --enable-slashpackage[=ROOT]  assume /package installation at ROOT [disabled]
+  --enable-absolute-paths       hardcode absolute BINDIR/foobar paths in binaries [disabled]
