+\`configure' configures this package to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:

+  --enable-sim-cflags=opts		Extra CFLAGS for use in building simulator
+  --enable-sim-debug=opts		Enable debugging flags

+
+Some influential environment variables:
+  CC          C compiler command
+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
+              nonstandard directory <lib dir>
+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+  CPP         C preprocessor
+
+Use these variables to override the choices made by `configure' or to help

+# First try --with-build-time-tools, if specified.
+#
+# For build != host, we ask the installed GCC for the name of the tool it

+# only good choice for a compiler is the same GCC version that is being
+# installed (or we couldn't make target libraries), and we assume that
+# on the host system we'll have not only the same GCC version, but also
+# the same binutils version.
+#
+# For build == host, search the same directories that the installed
+# compiler will search.  We used to do this for the assembler, linker,
+# and nm only; for simplicity of configuration, however, we extend this
+# criterion to tools (such as ar and ranlib) that are never invoked by
+# the compiler, to avoid mismatches.
+#
+# Also note we have to check MD_EXEC_PREFIX before checking the user's path
+# if build == target.  This makes the most sense only when bootstrapping,
+# but we also do so when build != host.  In this case, we hope that the
+# build and host systems will have similar contents of MD_EXEC_PREFIX.
