+ALGOL 68					*algol68* *ft-algol68-syntax*
+
+This syntax file currently targets the Algol 68 Genie project using the
+default UPPER stropping regime.  It should also be usuable in other
+environments using the UPPER stropping regime, though somewhat less complete.
+
+Highlighting can be further configured with the following variables.
+
+Variable			Highlight ~
+*algol68_no_preludes*		no prelude identifiers, procedures or
+				bold word operators
+*algol68_symbolic_operators*	all prelude symbolic operators
+
+
 ANT						*ant.vim* *ft-ant-syntax*
 
 The ant syntax file provides syntax highlighting for javascript and python

+    Algol 68 prelude identifier from the Genie source code files.
+    
+    Provided as a base to verify the correct syntax highlighting
+    of the algol68.vim syntax file for the Vim editor.
+    
+    There's four sections, each representing an original file,
+    that are enclosed in the Unix-'more' form to stand out.
+    
+    Some informal comments from the source code left intact as
+    a comment in Algol 68 syntax.
+    
+    Depending on the language context there's duplicates in the
+    list, that are kept for clarity given the associated informal
+    comment associated with them.
+    
+    Some entries deliberately contain two identifier variants that
+    may be used as alternative form in an Algol 68 Genie program.
+    
+    The identifiers are presented in two variants separated by a
+    tabulator; first with spaces, then in canonical form without
+    spaces. Variants with spaces are supported by the Vim syntax
+    file as the Algol 68 language does.
+    But note that while Algol 68 allows arbitrary spacing within
+    identifiers - even as extreme as writing one character per
+    line! - the Vim syntax file for Algol 68 had deliberately
+    been defined in a way restricting the highlighted options;
+    spacing can usually be inserted where "natural words" would
+    allow a separation (say for 'intwidth' you may write, e.g.,
+    'int width' but not 'int wid th'; the latter would not get
+    highlighted).
+    
+    Modelines are set to simply inspect the correct highlighting
+    in this file.
