* Coordinates download parameters and manages their dependencies
* prior to downloading them.
*
* Input can come from three sources:
*
* - local files (archives or package.xml)
* - remote files (downloadable urls)
* - abstract package names
*
* The first two elements are handled cleanly by PEAR_PackageFile, but the third requires
* accessing pearweb's xml-rpc interface to determine necessary dependencies, and the
* format returned of dependencies is slightly different from that used in package.xml.
*
* This class hides the differences between these elements, and makes automatic
* dependency resolution a piece of cake. It also manages conflicts when
* two classes depend on incompatible dependencies, or differing versions of the same
* package dependency. In addition, download will not be attempted if the php version is
* not supported, PEAR installer version is not supported, or non-PECL extensions are not
* installed.
