A repository for common objects of physical etoys.(09 Mar 2010) I removed the #initialize method from PEUtilities to avoid modifying the source code when installing, and I added some comments.(23 Dic 2009) Added a fix to StandardViewer>>#addViewerCategory to avoid adding an already included category.(17 Nov 2009) I added #makeNewFlapNamed:with: to PEUtilities.(16 Nov 2009) I added PEUtilities with the functionality of "About Physical Etoys" window.(11 Nov 2009) I added PESerialPortList (which handles the list of available serial ports in different platforms) and PEAttachmentPointMorph (a morph whose only purpose is esthetical). I also started using the "PE" prefix.Currently (25 Aug 2009), it only contains SimpleConnectorMorph, which I use to wire devices. It requires Connectors from Ned Konz.
