laser_filters cannot be found

Hi,

I am a newbie to ROS and I want to use some of the built-in filters to process the laser scan.

I installed the filters package before and I double checked today by typing: sudo apt-get install ros-indigo-laser-filters

it said: Reading package lists... Done Building dependency tree
Reading state information... Done ros-indigo-filters is already the newest version. ros-indigo-filters set to manually installed. The following packages were automatically installed and are no longer required: libgcal0 linux-headers-3.13.0-32 linux-headers-3.13.0-32-generic linux-image-3.13.0-32-generic linux-image-extra-3.13.0-32-generic ros-indigo-shape-tools Use 'apt-get autoremove' to remove them. 0 upgraded, 0 newly installed, 0 to remove and 20 not upgraded.

So the filters should have been installed right?

However, when I open the laser_filters folder in opt/ros/indigo/shared/, there are only a cmake folder and two xml files. From the tutorial there should be a "examples" folder inside the laser_filter folder.

Can anyone tell me if the laser_filters package was correctly installed? Where can I find the package?

Thanks in advance.
