+This directory contains Vim scripts for syntax highlighting.
+
+These scripts are not for a language, but are used by Vim itself:
+
+syntax.vim	Used for the ":syntax on" command.  Uses synload.vim.
+
+manual.vim	Used for the ":syntax manual" command.  Uses synload.vim.
+
+synload.vim	Contains autocommands to load a language file when a certain
+		file name (extension) is used.  And sets up the Syntax menu
+		for the GUI.
+
+nosyntax.vim	Used for the ":syntax off" command.  Undo the loading of
+		synload.vim.
+
+The "shared" directory contains generated files and what is used by more than
+one syntax.
+
+
+A few special files:
+
+2html.vim	Converts any highlighted file to HTML (GUI only).
+colortest.vim	Check for color names and actual color on screen.
+hitest.vim	View the current highlight settings.
+whitespace.vim  View Tabs and Spaces.
+
+
+If you want to write a syntax file, read the docs at ":help usr_44.txt".
+
+If you make a new syntax file which would be useful for others, please send it
+to the vim-dev mailing list <vim-dev@vim.org>.  Include instructions for
+detecting the file type for this language, by file name extension or by
+checking a few lines in the file. And please write the file in a portable way,
+see ":help 44.12".
+
+If you have remarks about an existing file, send them to the maintainer of
+that file.  Only when you get no response send a message to the vim-dev
+mailing list: <vim-dev@vim.org>.
+
+If you are the maintainer of a syntax file and make improvements, send the new
+version to the vim-dev mailing list: <vim-dev@vim.org>
