- `configure' configures this package 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
- --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

- `/usr/local/bin', `/usr/local/lib' etc. You can specify
- an installation prefix other than `/usr/local' using `--prefix',
- for instance `--prefix=$HOME'.
