'configure' configures tudu-0.10.4 to adapt to many kinds of systems.

Usage: ./configure [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
  -V, --version           display version information and exit
  -r, --report            show what libs/programs require to work

Installation directories:
  --prefix=PREFIX        install arch-independent files in PREFIX [/usr/local]
  --exec-prefix=EPREFIX  install arch-dependent files in EPREFIX [PREFIX]
  --sandbox=SPREFIX      sandbox prefix directory: SPREFIX [PREFIX]

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]
  --datadir=DIR          read-only architecture-independent data [PREFIX/share]
  --sysconfdir=DIR       read-only single-machine data [PREFIX/etc]
  --sharedstatedir=DIR   modifiable architecture-independent data [PREFIX/com]
  --localstatedir=DIR    modifiable single-machine data [PREFIX/var]
  --libdir=DIR           object code libraries [EPREFIX/lib]
  --includedir=DIR       C header files [PREFIX/include]
  --infodir=DIR          info documentation [DATADIR/info]
  --mandir=DIR           man documentation [DATADIR/man]

System types:
  --build=BUILD          configure for building on BUILD [guessed]
  --host=HOST            cross-compile to build programs to run on HOST [BUILD]
  --target=TARGET        configure for building compilers for TARGET [HOST]
