This script requires PEAR (http://www.pear.net) and the Archive_Tar and Text_Diff packages to be installed.

To install these in most Linux environments:

sudo pear install Archive_Tar

sudo pear install Text_Diff

USAGE: php coreagent.php <drupal_installation_dir (optional)>

To use the shell script version, you first need to set the execute bit:

chmod a+x coreagent

NOTE: This has not been tested on PHP for Windows, and probably won't work
