Classe: PEAR_Task_Common - X-Ref

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.

<file name="test.php" role="php">
<tasks:replace from="@data-dir@" to="data_dir" type="pear-config"/>
<tasks:postinstallscript/>
</file>

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.
