+" Vim syntax file
+" Language:	Euphoria 4.0.5 (http://www.RapidEuphoria.com)
+" Maintainer:	Shian Lee  
+" Last Change:	2014 Feb 23 (for Vim 7.4)
+" Remark:       Using 'euphoria3.vim' if "$EUDIR\BIN\EX.EXE" or "$EUDIR/bin/exu" 
+"               file exist; else, using 'euphoria4.vim' for Euphoria 4.x.x.
+" Filetype:     *.e, *.eu, *.ew, *.ex, *.exu, *.exw (also in UPPER case).
+"               note: *.e|*.E are used by Eiffel; for solution see :help filetype. 
+
+" Quit if a (custom) syntax file was already loaded (compatible with Vim 5.8): 
+if version < 600
+  syntax clear
+elseif exists("b:current_syntax")
+  finish
+endif
+
+" Should suffice for very long strings and expressions:
+syn sync lines=40
+
+" Euphoria is a case-sensitive language (with only 4 builtin types):
