Can't get '--coverage-html' switch to work in PHPUnit2

[mirnazim@gmail.com]

hi,
how do I use code coverage and test skeleton generators to work in
PHPUnit2.
I used following commands

1) phpunit --coverage-html SomeTest

2) phpunit --skeleton SomeClass

as described at http://www.phpunit.de/en/phpunit2_codecoverage.php and
http://www.phpunit.de/en/phpunit2_skeleton.php, but it is not working.

Please Help.
Thanks
