If you prefer to install Jalopy manually yourself, you can extract the contents of the archive with your favorite zip utility and copy the different files and/or folders to the appropriate locations.
Please note that Wizard installation is mandatory for the JDeveloper and NetBeans Plug-ins!
Unzipping will produce several files and directories, but not all files are actually needed by all users.
Refer to the different Plug-in chapters in Part II, "Plug-ins" for further information where the files and/or directories need to be placed.
