To use your new extension, you will have to execute the following steps:

1. $ cd ..
2. $ vi ext/$extname/config.m4
3. $ ./buildconf
4. $ ./configure --[with|enable]-$extname
5. $ make
6. $ ./php -f ext/$extname/$extname.php
7. $ vi ext/$extname/$extname.c
8. $ make

Repeat steps 3-6 until you are satisfied with ext/$extname/config.m4 and
step 6 confirms that your module is compiled into PHP. Then, start writing
code and repeat the last two steps as often as necessary.
