                summary="In computing, the Post Office Protocol (POP) is an application-layer Internet standard protocol used by local e-mail clients to retrieve e-mail from a remote server over a TCP/IP connection. POP and IMAP (Internet Message Access Protocol) are the two most prevalent Internet standard protocols for e-mail retrieval. Virtually all modern e-mail clients and servers support both. The POP protocol has been developed through several versions, with version 3 (POP3) being the current standard."

                summary="Marketplace Client is a rich client solution for installing solutions listed on Eclipse Marketplace directly from an Eclipse Installation.&#x0A;&#x0A;The Eclipse community has hundreds, if not thousands, of third-party plugins that users can add to their Eclipse installation. Unfortunately, there is not easy way to discover and install these solutions from within Eclipse.&#x0A;&#x0A;The Eclipse Foundation has recently launched a new website, called Eclipse Marketplace, that provides a listing of Eclipse-based solutions. The listings allow each solution provider to specify a P2 repository for their solution. Eclipse users now have a central catalog to find Eclipse solutions but the install process is still not tightly integrated with the Eclipse workspace.&#x0A;&#x0A;MPC provides the tight install integration between the Eclipse workspace and Eclipse Marketplace, plus other third party solution listings. MPC is included in many of the EPP packages."
