+This is the installation program of the TeX Live distribution.
+
+The installation procedure is simple: just go through the
+menus until you are happy with the way all options are set up,
+and then do <I> (start installation).
+
+To select a menu item (a letter or a number marked with brackets)
+just enter the corresponding letter or number and press return
+(the letters are case insensitive except when collections
+are being selected). Do not enter the 
+angle brackets <> themselves.
+
+We will now consider each menu item in more detail:
+
+======================================================================
+  The collections menu (<C>)
+======================================================================
+
+The collections menu allows you to select and deselect standard
+collections. Each collection --- TeX macro files, Metafont font
+families, and so on --- consists of several packages.
+
+======================================================================
+  The language collections menu (<L>)
+======================================================================
+
+The language collections menu allows you to select and deselect
+language support collections. Each collection consists of several
+packages, which provide features like hyphenation files and fonts.
+
+======================================================================
+  The binary systems menu (<B>)
+======================================================================
+
+The systems menu allows you to select and deselect 
+the binary packages for various different platforms.
+
+======================================================================
+  The directories menu (<D>)
+======================================================================
+
+The TeX Live distribution will be installed in a single directory tree
+(TEXDIR). You may choose any directory you like
+since there are no absolute paths compiled into the binaries. Instead,
+the Kpathsea library selfdir feature ensures that all
+paths are relative to the location of the binaries.
+
+The platform independent files are stored in a directory tree in
+TEXDIR/texmf. There is also an extra directory for performing
+administrative tasks like change of configuration and languages. This
+is where all format files are stored. It defaults to TEXDIR/texmf-var.
+
+This system allows you to mount your
+TEXDIR/texmf tree read-only.
+
+======================================================================
+  The options menu (<O>)
+======================================================================
+
+The options are not applicable to all installations.  Set them as
+appropriate for yours.
+
+======================================================================
+  The schemes menu (<S>)
+======================================================================
+
+You can choose from a number of different installation
+schemes for TeX Live. Selecting one of these selects
+some collections in the Collections and Languages lists.
+which you can subsequently modify.
+
+"alternate fonts directory":
+============================
+
+You can choose an alternate directory for automatically generated fonts;
+the default is TEXMFSYSVAR/fonts
+
+One disadvantage may be that new fonts are not shared.  I.e., if you
+set this to /tmp, and users on two different machines need the same
+font, it will be built twice, once on each machine.
+
+"symlinks in standard directories"
+==================================
+
+You can make the binaries, man pages, and info files available on your
+system in either (or both) of two ways:
+  1) install them in "standard places" that are searched for these files
+  2) change your search paths to include the new directories
+
+If you select the "symlinks" option, symbolic links will be installed in
+the directories you choose. Note that if you share the TeX Live installation
+accross several machines across NFS and if the chosen "standard places" are
+not shared, you need to create the symbolic links on each client, too
+(or use method 2 on your clients).
+
+If you do not use the "symlinks" option, you probably need to set up
+your search paths (PATH, MANPATH, INFOPATH).
+
+"do not install doc or source trees"
+====================================
+These options are not recommended, but you can use them to save space. 
+Normally all packages are installed with the source and/or documentation,
+but these are not needed to actually run the software. If you
+are installing a system for other people, it would be unfriendly to
+select these options; if you know what you are doing and need a
+minimal disk footprint, go ahead
+
+
+======================================================================
+  Other commands (<I>, <H>, <R> and <Q>
+======================================================================
+
+Well, this is easy to explain:
+  <R> does not install the system, but sets you to run off the CD
+  <I> starts the installation after you are happy with the setup
+  <H> displays this help
+  <Q> quits the installation program
