+"---------------------\n"

+"This makes it possible to start Vim from the command line.\n"
+"If vim.exe can be found in $PATH, the choice for vim.bat will not be\n"
+"present. It is assumed you will use the existing vim.exe.\n"
+"If vim.bat can already be found in $PATH this is probably for an old\n"
+"version of Vim (but this is not checked!). You can overwrite it.\n"
+"If no vim.bat already exists, you can select one of the directories in\n"
+"$PATH for creating the batch file, or disable creating a vim.bat file.\n"
+"\n"
+"If you choose not to create the vim.bat file, Vim can still be executed\n"
+"in other ways, but not from the command line.\n"
+"\n"
+"The same applies to choices for gvim, evim, (g)view, and (g)vimdiff.\n"
+"The first item can be used to change the path for all of them.\n"
+,
+"Creating a _vimrc file\n"
+"----------------------\n"
+"The _vimrc file is used to set options for how Vim behaves.\n"
+"The install program can create a _vimrc file with a few basic choices.\n"
+"You can edit this file later to tune your preferences.\n"
+"If you already have a _vimrc or .vimrc file it can be overwritten.\n"
+"Don't do that if you have made changes to it.\n"
+,
+"Vim features\n"
+"------------\n"
+"(this choice is only available when creating a _vimrc file)\n"
+"1. Vim can run in Vi-compatible mode. Many nice Vim features are then\n"
+" disabled. In the not-Vi-compatible mode Vim is still mostly Vi\n"
+" compatible, but adds nice features like multi-level undo. Only\n"
+" choose Vi-compatible if you really need full Vi compatibility.\n"
+"2. Running Vim with some enhancements is useful when you want some of\n"
+" the nice Vim features, but have a slow computer and want to keep it\n"
+" really fast.\n"
+"3. Syntax highlighting shows many files in color. Not only does this look\n"
+" nice, it also makes it easier to spot errors and you can work faster.\n"
+" The other features include editing compressed files.\n"
+,
+"Windows key mapping\n"
+"-------------------\n"
+"(this choice is only available when creating a _vimrc file)\n"
+"Under MS-Windows the CTRL-C key copies text to the clipboard and CTRL-V\n"
+"pastes text from the clipboard. There are a few more keys like these.\n"
+"Unfortunately, in Vim these keys normally have another meaning.\n"
+"1. Choose to have the keys like they normally are in Vim (useful if you\n"
+" also use Vim on other systems).\n"
+"2. Choose to have the keys work like they are used on MS-Windows (useful\n"
+" if you mostly work on MS-Windows).\n"
+,
+"Mouse use\n"
+"---------\n"
+"(this choice is only available when creating a _vimrc file)\n"
+"The right mouse button can be used in two ways:\n"
+"1. The Unix way is to extend an existing selection. The popup menu is\n"
+" not available.\n"
+"2. The MS-Windows way is to show a popup menu, which allows you to\n"
+" copy/paste text, undo/redo, etc. Extending the selection can still be\n"
+" done by keeping SHIFT pressed while using the left mouse button\n"
+,
+"Edit-with-Vim context menu entry\n"
+"--------------------------------\n"
+"(this choice is only available when gvim.exe and gvimext.dll are present)\n"
+"You can associate different file types with Vim, so that you can (double)\n"
+"click on a file to edit it with Vim. This means you have to individually\n"
