Configure script for $PROJECT_NAME $PROJECT_VERSION 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.

Options:

  --help                display this help and exit

Installation directories:

  --prefix=PATH         install architecture-independent files in PATH
  --exec-prefix=PATH    install architecture-dependent files in PATH

Fine tuning of the installation directories:

  --bindir=PATH         user executables
  --sbindir=PATH        system admin executables
  --datarootdir=PATH    read-only arch.-independent data root
  --datadir=PATH        read-only architecture-independent data
  --sysconfdir=PATH     read-only single-machine data
  --sharedstatedir=PATH modifiable architecture-independent data
  --localstatedir=PATH  modifiable single-machine data

Some influential environment variables:

  SHELL                 shell command
  CC                    C compiler command
  BISON                 Bison compiler command
  RM                    rm command
  RMDIR                 rmdir command
  TEST                  test command
  MAKE                  make command
  GREP                  grep command
  CUT                   cut command
  SORT                  sort command
  PR                    pr command

  CFLAGS                C compiler flags
  LDFLAGS               linker flags, e.g. -L<lib dir> if you have
                        libraries in a nonstandard directory <lib dir>
  LDLIBS                libraries to pass to the linker, e.g. -l<library>
  BFLAGS                Bison compiler flags

Use these variables to override default values.
