+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]
