+ * A task is an operation that manipulates the contents of a file.
+ *
+ * Simple tasks operate on 1 file. Multiple tasks are executed after all files have been
+ * processed and installed, and are designed to operate on all files containing the task.
+ * The Post-install script task simply takes advantage of the fact that it will be run
+ * after installation, replace is a simple task.
+ *
+ * Combining tasks is possible, but ordering is significant.
+ *
+ *
+ *
+ *
+ *
+ *
+ * This will first replace any instance of @data-dir@ in the test.php file
+ * with the path to the current data directory. Then, it will include the
+ * test.php file and run the script it contains to configure the package post-installation.
