PEAR Channels
A PEAR Channel is a web site that distributes
package archives for remote
installation by users of Pyrus or the PEAR Installer. In addition to providing
the package archives for download, a PEAR Channel must also provide some
meta-information that the installer can use to locate the package releases and
determine which is the best release to download.
Channels have a file that defines the capabilities of the channel named
channel.xml located in its
document root (for instance,
pear.php.net's channel.xml)
and some meta-information in REST format.
A channel can also provide a public frontend for users to browse the contents
of the channel online, such as
PEAR's public frontend.
