aka:GNU Autotools

メモ
- My package doesn't contain the configure script. What should I do?
  - You should create your configure script with Autotools.
  - For example on OSX with MacPorts to create it for lookup, instructions are like below.
```
$ sudo port automake autoconf autoconf-archive
$ cd lookup
$ automake --add-missing
$ aclocal
$ autoreconf
$
```
