ac_usage="Usage: configure [options] [host]

Options: [defaults in brackets after descriptions]

Configuration:

--cache-file=FILE cache test results in FILE

--help print this message

--no-create do not create output files

--quiet, --silent do not print \`checking...' messages

--version print the version of autoconf that created configure

Directory and file names:

--prefix=PREFIX install architecture-independent files in PREFIX

[$ac_default_prefix]

--exec-prefix=PREFIX install architecture-dependent files in PREFIX

[same as prefix]

--srcdir=DIR find the sources in DIR [configure dir or ..]

--program-prefix=PREFIX prepend PREFIX to installed program names

--program-suffix=SUFFIX append SUFFIX to installed program names

--program-transform-name=PROGRAM run sed PROGRAM on installed program names

Host type:

--build=BUILD configure for building on BUILD [BUILD=HOST]

--host=HOST configure for HOST [guessed]

--target=TARGET configure for TARGET [TARGET=HOST]

Features and packages:

--disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)

--enable-FEATURE[=ARG] include FEATURE [ARG=yes]

--with-PACKAGE[=ARG] use PACKAGE [ARG=yes]

--without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)

--x-includes=DIR X include files are in DIR

--x-libraries=DIR X library files are in DIR
