The PSWBTM sub-tree should be optional, only included with the engine-tester profile. Preferably in such a way that it is not even downloaded, as it is huge, and only very few people would want it.
For the rest the optional components are not very big, and might as well be all in the initial download, and then not installed if people did not want them. Those are: Variantist profile: joker/* pulsar/* SMIRF/* Xiangqi profile: HaQi/* EleEye/* WinBoard/QH2WB.exe WinBoard/textures/xqwood.bmp WinBoard/xq_book.bin Fruit: Fruit/* The rest of the components should be in the basic install. Note that the current installer.zip does not contain the final versions of some files, as we have had some upgrades of WinBoard in the mean time.
