+\`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:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]

+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

+ LIBS libraries to pass to the linker, e.g. -l<library>
+ CPPFLAGS C/C++/Objective C preprocessor flags, e.g. -I<include dir> if

+# For build != host, we ask the installed GCC for the name of the tool it

+# For build == host, search the same directories that the installed

+# 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.

+/* A note about endianness and swapping...
+
+ The RX chip is CISC-like in that the opcodes are variable length
+ and are read as a stream of bytes. However, the chip itself shares
+ the code prefetch block with the data fetch block, so when it's
+ configured for big endian mode, the memory fetched for opcodes is
+ word-swapped. To compensate for this, the ELF file has the code
+ sections pre-swapped. Our BFD knows this, and for the convenience
+ of all the other tools, hides this swapping at a very low level.
+ I.e. it swaps words on the way out and on the way back in.
+
+ Fortunately the iovector routines are unaffected by this, so we
+ can use them to read in the segments directly, without having
+ to worry about byte swapping anything.
+
+ However, our opcode decoder and disassemblers need to swap the data
+ after reading it from the chip memory, just like the chip does.
+ All in all, the code words are swapped four times between the
+ assembler and our decoder.
+
+ If the chip is running in little-endian mode, no swapping is done
+ anywhere. Note also that the *operands* within opcodes are always
+ encoded in little-endian format. */
