Tasks are periodic, short-running jobs.
<cmd> and <period> are required.
OUTPUT specifies the file to output and by default is COMMAND_BASE_NAME.out.
Commands are run in the <bin_dir> directory
which is a path relative to <project_dir> and output to <log_dir>.
Daemons are continuously-running programs. The process ID is recorded in the <pid_dir> directory and the process is sent a SIGHUP in a DISABLE operation.
Both tasks and daemons can run on a different host (specified by <host>). The default is the project's main host, which is specified in config.host A daemon or task can be turned off by adding the <disabled> element. As well, there may be some tasks you wish to run via cron regardless of whether or not the project is enabled (for example, a script that logs the current CPU load of the host machine). You can do so by adding the <always_run> element (<disabled> takes precedence over <always_run>). "; page_tail(); ?>
