Description:
------------
Running 'ext/ext_skel' as per the instructions here:

http://php.net/manual/en/internals2.buildsys.skeleton.php

Outputs something like this:

---
Creating directory sync
Creating basic files: config.m4 config.w32 .svnignore sample.c php_sample.h CREDITS EXPERIMENTAL tests/001.phpt sample.php [done].

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

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

Repeat steps 3-6 until you are satisfied with ext/sync/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.

Line 6 appears to be incorrect.  The PHP binary is not found in the root directory.

Expected result:
----------------
Line 6 should read:

6.  $ ./sapi/cli/php -f ext/sample/sample.php
