The thing is that besides the JDK itself I haven't see Java applications shipping man pages so far (reasons are easy to guess). As for the executable versioning, yes we version the executables if it's useful to install multiple versions at the same time. Most of the time it's only prudent to keep the executable in the latest version and libraries for the old versions. For example if the different versions use the same subdirectory in /home then it would be dangerous to let the user mix versions like that but in the case of for example Netbeans it's safe as the settings directory is versioned so there is for example: /usr/bin/netbeans-5.5 Regards, Petteri
